A-Mr. Orfeo, the Boulder
The doubling keys off the attack declaration rather than a specific attacker, and that is the design's actual leverage: you pick the target when attackers are declared, so the biggest thing you have does not need to be the thing that gets the boost, and this Rhino can sit back on defense while your other creatures swing. Point the effect at whichever attacker profits most from a spiked power number, then repeat it every combat you reach. That renewal is the whole strategic axis. A one-shot pump spell spends itself; this recurs on a permanent, so its ceiling is a function of how many attack steps you survive to declare, not any single doubling. The timing is scripted, not surprising: the buff lands during the declare-attackers step and expires at end of turn, so it is a spike on a fixed schedule you cannot hold up as a bluff. A 3/4 body across three colors is a modest frame for what is really a repeatable finisher-enabler; the effect wants a partner with evasion or a board wide enough that one sudden doubling closes the game. As a digital-only rebalance made for Arena's Alchemy formats, it sits on the seam between recurring combat engine and standing threat: a creature that hands you a fresh power spike whenever you commit to combat, whether or not it is the one throwing the punch.
