At the beginning of combat on your turn, another target creature you control gains haste and myriad until end of turn. (Whenever it attacks, for each opponent other than defending player, you may create a token copy that's tapped and attacking that player or a planeswalker they control. Exile the tokens at end of combat.)
Pick a creature with a powerful combat or attack trigger, give it myriad each turn, and swing at all three opponents at once to multiply that trigger across the board. You ramp toward big threats, protect your key attacker, and turn a single connect into overwhelming damage, tokens, or value before the copies are exiled.
Prioritize creatures whose attack or combat-damage triggers scale explosively with copies (Etali, Hellkite Tyrant, Combat Celebrant) and add extra-combat enablers like Aurelia and Aggravated Assault. Shore up Boros's weaknesses with fast mana (Sol Ring, Smothering Tithe, Treasure makers) and card advantage from impulse draw. Include protection like Heroic Intervention and ways to force damage through such as Bedlam and trample to maximize myriad payoffs.
