Additive Evolution (SOS)

Enchantment

When this enchantment enters, create a 0/0 green and blue Fractal creature token. Put three +1/+1 counters on it. At the beginning of combat on your turn, put a +1/+1 counter on target creature you control. It gains vigilance until end of turn.

Reliable growth engine for +1/+1 counter and Simic strategies. Additive Evolution enters with an immediate 3/3 flyer threat and then provides consistent pump and vigilance every turn, letting you attack without sacrificing your defense. The repeatable effect scales well in Commander and works efficiently in Pioneer/Modern midrange decks that already care about counters, though it's vulnerable to removal and requires a turn to set up. Best in decks with other counter synergies or evasive creatures that benefit from vigilance.
