Haste
,
: Copy target activated or triggered ability you control from another legendary source that's not a commander. You may choose new targets for the copy. (Mana abilities can't be targeted.)
Cast The Peregrine Dynamo turn 3 and use its haste to start copying powerful activated and triggered abilities from your legendary permanents, effectively doubling planeswalker activations, legendary creature ETBs/attack triggers, and artifact/Saga abilities. You build a board of impactful legendaries, then chain copies to snowball value and resources until you assemble a lethal or game-locking engine.
Add untap enablers like Voltaic Construct, Manifold Key, and Aphetto Alchemist to copy multiple abilities per turn, and lean into fast colorless ramp (Sol Ring, Mana Crypt, Grim Monolith) to deploy Dynamo and legendaries early. Tighten the legendary count so you always have strong copy targets, and include protection like Lightning Greaves or Swiftfoot Boots to keep the engine alive against removal.
