Whenever you cast a spell, you gain 1 life for each spell you've cast this turn.

Pay 50 life: Aetherflux Reservoir deals 50 damage to any target.

Search your library for a white card, a blue card, a black card, a red card, and a green card. Reveal those cards, put them into your hand, then shuffle.

All artifacts have "At the beginning of your upkeep, sacrifice this artifact unless you pay ."

Haste

Whenever Fireflux Squad attacks, you may exile another target attacking creature you control. If you do, reveal cards from the top of your library until you reveal a creature card. Put that card onto the battlefield tapped and attacking and the rest on the bottom of your library in a random order.

Whenever you cast a noncreature spell, proliferate. (Choose any number of permanents and/or players, then give each another counter of each kind already there.)

Paradox — Impending Flux deals X damage to each opponent and each creature they control, where X is 1 plus the number of spells you've cast from anywhere other than your hand this turn.

Foretell (During your turn, you may pay and exile this card from your hand face down. Cast it on a later turn for its foretell cost.)

, Remove one or more +1/+1 counters from among creatures you control: Create an X/X green Ooze creature token, where X is the number of +1/+1 counters removed this way.

Evolve (Whenever a creature enters the battlefield under your control, if that creature has greater power or toughness than this creature, put a +1/+1 counter on this creature.)

, : Move a +1/+1 counter from Simic Fluxmage onto target creature.

Choose one —

• Target nonsnow permanent becomes snow until end of turn.

• Target snow permanent isn't snow until end of turn.

Draw a card at the beginning of the next turn's upkeep.
