Prototype {1}{U}{U} — 2/1 (You may cast this spell with different mana cost, color, and size. It keeps its abilities and types.) When this creature enters, if you cast it, exile target instant or sorcery card with mana value less than or equal to this creature's power from your graveyard. Copy that card. You may cast the copy without paying its mana cost.

Lifelink, toxic 1 Whenever you proliferate, choose one — • If you don't control a creature named The Hollow Sentinel, create The Hollow Sentinel, a legendary 3/3 colorless Phyrexian Golem artifact creature token. • Target artifact creature you control gains flying and lifelink until end of turn.

Exile target creature if it has mana value 3 or less. Corrupted — Exile that creature instead if its controller has three or more poison counters.

Look at the top three cards of your library. Put one of them into your hand and the rest on the bottom of your library in any order. Proliferate. (Choose any number of permanents and/or players, then give each another counter of each kind already there.)

Each opponent gets a poison counter. Draw a card.

Return target nonland permanent to its owner's hand. If that permanent had mana value 3 or less, proliferate. (Choose any number of permanents and/or players, then give each another counter of each kind already there.)

This land enters tapped unless you control two or fewer other lands. {T}: Add {U} or {B}.

{T}: Add {U}. {T}: Add {B}. Activate only if you control an Island or a Swamp.

({T}: Add {U}.)

{T}: Add {C}. {T}: Add one mana of any color. Activate only if this land entered this turn. {3}, {T}: Create a 1/1 colorless Phyrexian Mite artifact creature token with toxic 1 and "This token can't block." (Players dealt combat damage by it also get a poison counter.)

({T}: Add {B}.)

As an additional cost to cast this spell, you may collect evidence 6. Destroy all creatures. If evidence was collected, exile a card from an opponent's graveyard. Then search its owner's graveyard, hand, and library for any number of cards with that name and exile them. That player shuffles, then draws a card for each card exiled from their hand this way.

Target creature gets -4/-4 until end of turn. Proliferate. (Choose any number of permanents and/or players, then give each another counter of each kind already there.)

All creatures get -2/-2 until end of turn. If a creature an opponent controls would die this turn, exile it instead.
