Rhoda, Geist Avenger
Most white beaters grow by attacking or by their own tap abilities; this one grows on the opponent's dime, feeding on the tapping they choose to do. The trigger keys off any creature an opponent controls becoming tapped for a reason other than declaring an attack: crewing a Vehicle, activating a mana dork, convoking a spell, tapping down for a pump ability, or being tapped by a spell or effect. Each of those quietly hands over a +1/+1 counter. The explicit "if it isn't being declared as an attacker" clause is the tension that makes the design coherent: it stops the card from punishing the one tapped state opponents can't avoid in combat, and instead taxes the incidental tapping that fair decks lean on to function. Vigilance keeps the accumulated body relevant on both sides of the turn, so the counters don't sit idle while it holds back. What the ability ultimately reads as is a passive tax on interaction and utility, a soldier that penalizes an opponent for using their own board as anything but attackers. Paired with Timin, Youthful Geist through partner, it's built to headline a group of tap-matters incentives rather than to carry a game alone, a punisher whose growth curve is dictated entirely by how much the table wants to tap things.
