Crag Puca

Natively a 2/4, it blocks well and attacks poorly, which is precisely the half the switch ability is built to renegotiate. Leave mana untapped on your own turn and the wall becomes a 4-power attacker; hold the same mana on the opponent's turn and the body threatens to block as a 4/2, mauling whatever they sent in. Every flip reverts when the turn ends, so the creature never commits to one role: it rents the stat line the current combat step demands and gives it back. That instant-speed reconfiguration is what pays for an otherwise plain body, since no attacker or blocker can ever reliably size combat against a creature that rewrites itself in response to their decision. It is a self-contained combat puzzle, the kind of design that asks the pilot to read the math two steps deep and keep mana back for the flip rather than spending it elsewhere. The hybrid pips reinforce the joke: a mono-color shell can both cast it and activate it on either side of its blue-or-red identity, so the switch is never gated behind a second color. The Shapeshifter type fits less for tribal payoff than for the literal premise: a creature whose only trick is becoming a slightly different creature exactly when that difference would matter.
