Whenever Brago deals combat damage to a player, exile any number of target nonland permanents you control, then return those cards to the battlefield under their owner's control.
Connect with Brago's evasive 2/4 flyer, then blink your own nonland permanents to re-trigger their enter-the-battlefield abilities every combat. You snowball card advantage, board control, and untapped mana off ETB engines until you lock the table or assemble a loop that wins. The early game is ramp, protection, and value blinkers; the mid-game is a Brago hit that buries opponents in value.
Repeatable ETB abuse generates massive card and board advantage each turn
Can untap mana rocks and lands (via Deadeye Navigator-style or blinking rocks) to power explosive turns
Resets your own permanents to dodge auras, counters, and removal targeting
Hexproof and haste protect Brago and let him attack the turn he resolves.
Add evasion and protection for Brago (Aqueous Form, Rogue's Passage, Lightning Greaves) so he connects consistently, then build toward a clean combo finish via Strionic Resonator with Peregrine Drake/Great Whale plus a flicker-payoff like Altar of the Brood. Tighten the mana base with fast rocks and ramp, and lean into stax pieces (Winter Orb, Static Orb) that hurt opponents more than you since you blink for free value.
