Haste
Whenever one or more other attacking legendary creatures you control die, untap all creatures you control. After this phase, there is an additional combat phase. This ability triggers only once each turn.
Flood the board with legendary creatures, swing in, then sacrifice or trade an attacking legend to untap everything and get a bonus combat phase for a lethal second swing. Éomer wants aggressive, repeatable extra combats fueled by cheap legends and sacrifice outlets, closing games before opponents stabilize.
Add fast mana (Mana Crypt, Sol Ring, Jeska's Will) and free sacrifice outlets to consistently fire the trigger turn after turn. Layer in additional extra-combat enablers (Aggravated Assault, Moraug, Fury of Akoum) and efficient legendary token producers to scale damage, and include tutors like Gamble plus payoff finishers such as Impact Tremors to win even through chump blocks.
