Interesting Interactions

Exiling cards doesn't count as drawing, so you cannot lose (or win) by casting an AoI when 2 cards remain in your library. Cards exiled with Act on Impulse can be cast, but their activated abilities cannot be used as if they were in your hand. For example, a Street Wraith cannot be cycled from an Act on Impulse exile.

For Thassa's Oracle this can name Merfolk or Wizard. This will let you cast an Oracle through Chalice of the Void on X=2.

Only target a card if you must, never do it just for value, because if the targeted card is removed from the graveyard by your opponent then the bauble activation will fizzle and you will not draw a card.

Chromatic Sphere's activated ability is a mana ability. Mana abilities do not go on the stack, therefore your opponent cannot respond to this activation. Chromatic Sphere allows you to play around creature removal with Laboratory Maniac piles because you can play Chromatic Sphere, Laboratory Maniac, and then activate Chromatic Sphere without your opponent having priority to cast their removal.

If you have a land drop available. You can use Daze to generate additional mana by playing a dead card like Dark Ritual in order to return an Island to enable generation of two blue mana.

Doomsday rounds up the life loss so casting it at 1 life will result in you losing.

Lake of the Dead does not enter the battlefield until after a swamp is sacrificed. Therefore, it is not possible to do any tricks like activating it in response to that trigger. You really do need 2 swamps in play in order to activate this card, and those swamps will be sacrificed by playing and activating it. Lake of the Dead's activation is a mana ability and does not go on the stack either.

As in any Storm deck, LED can be cracked in response to draw effects and cantrips such as Brainstorm, Ponder, Preordain, and Conjurer's Bauble. Holding priority while casting these cantrips will allow you to crack the LED and discard your hand but still have the mana as you draw in to the next card of your library. Failing to announce that you are holding priority will prevent you to get the LED mana before you draw the cards.

This can target the opponent but can be stopped by Veil of Summer if you use choose to do so.

Oracle checks the devotion on resolution so if you have cards left in your library and your opponent kills the Oracle, you will have no devotion and not win the game. The Oracle checks on an equal to or less than basis so if you have no devotion and no cards in your library you will still win the game.

Veil of Summer will prevent any Thought Scour or Predict effects from targeting you. Conversely, it will not stop Mindbreak Trap, Stifle or Surgical Extraction from being effective. It will also draw you a card most of the time so be careful to keep this in mind if you have 0 cards left in your deck. This card will also let you play cards through a Chalice of the Void.

If there is an Aven Mindcensor on the board, a resolved Doomsday will be able to search only the top 4 cards of the library and the entire graveyard. Selecting 1 card from the top 4 does not allow you to dig one deeper in to your library.

If playing against a known Echo deck try to make sure you have at least 8 cards spread across your hand, library and graveyard to avoid them being able to Echo you to death. You should have a minimum of 6 from the Doomsday in your graveyard and your 5-cards pile so having an extra 2 cards in hand or some uncracked fetchlands and/or lotus petals in play can help achieve this.

An opponent can cause headaches with an Aether Vial on 3 and a Flickerwisp in hand, since they are able to exile cards at critical times in your sequencing. The disruptive cards that Flickerwisp can exile are LED, Conjurer's Bauble, Chromatic Sphere, Laboratory Maniac, or even a land in response to an unresolved Rain of Filth on the stack or to deny a Massacre alternative casting.

Casting Doomsday into an active Opposition Agent will result in your opponent getting to look for 5 cards in your deck and you exiling the rest. Unless Oracle is in your hand this will mostly result in your loss.

Pithing needle cannot stop LED, Lotus Petal, Chromatic Sphere, or Doomsday.

Players try naming Doomsday due to the strange wording on the Weatherlight printing since it appears like activated abilities do.

Pithing needle can stop Conjurer's Bauble, cyclers like Street Wraith and fetchlands.

Phyrexian Revoker can stop LED, Lotus Petal, Chromatic Sphere, Conjurer's Bauble and cyclers like Street Wraith. It cannot hit fetchlands nor Shelldock Isle.

These cards have the ability to disturb the ordering or contents of your library at instant speed, when you draw into your pile.

Can reorder your library at sorcery speed. Interferes with PTT piles.

If against Show and Tell you can build a pile that, if they cast a Show and Tell, you can cycle and put Oracle into play from it, winning with the trigger.

Remember that Death and Taxes can present removal by having an Aether Vial set to 3, even if they have no mana open. Be careful if considering a pile with cards remaining in your library.

Can stop Conjurer's Bauble activations, Tendrils of Agony and Empty the Warrens Storm triggers, as well as fetchlands, cyclers like Street Wraith and more importantly Thassa's Oracle triggers. Does not stop Chromatic Sphere, Lake of the Dead, Rain of Filth, Lotus Petal, or LED activations.

You cannot cast something using Shelldock Isle if the opponent has a Teferi in play however you can use Shelldock Isle to put a land into play.

These cards can put cards back into your pile. The former will make all your usual ways of digging into or thinning the pile useless ie. fetchlands, cantrips and cyclers won't reduce the size of your pile anymore. While the latter cast with the Oracle trigger still on the stack, will reduce your devotion to by 2 in addition to increasing the size of your library by one.
