Hideaway usually reads as a payoff mechanic bolted onto a fragile enabler: something small and cheap that squirrels a card away and dares you to keep it alive long enough to satisfy a narrow release condition. This inverts that arrangement entirely. The condition is not a threshold or a life total or a specific board state; it is combat damage to a player, and the body doing the connecting is a 6/5 with trample, which is already the kind of creature that connects on its own terms. The two hideaway triggers stack two exiled cards under it, so a single unblocked swing turns into a free cast, and the trample keeps chip damage flowing even into a chump. What balances it is the delay and the randomness: you look at three, keep one, and the two you buried on the bottom in random order are gone from your near-term draws. You are trading dig for a free spell that only pays out when the Bear gets through, which means every point of interaction aimed at it is also interaction aimed at your buried card. The card most worth exiling is a bomb you could never afford honestly, and the ideal build wants the top of the library stacked with exactly those, so the hideaway looks at the right three. The strategic axis is not the beater; it is what a big green creature earns you for the crime of hitting a player.
