Nanogene Conversion

Choose target creature you control. Each other creature becomes a copy of that creature until end of turn, except it isn't legendary.

Bearer of the Heavens

When this creature dies, destroy all permanents at the beginning of the next end step.

Plargg and Nassari

At the beginning of your upkeep, each player exiles cards from the top of their library until they exile a nonland card. An opponent chooses a nonland card exiled this way. You may cast up to two spells from among the other cards exiled this way without paying their mana costs.

Gather Specimens

If a creature would enter the battlefield under an opponent's control this turn, it enters under your control instead.
