ED-E, Lonesome Eyebot

A wide-attack ratchet dressed up as a companion. Quest counters only accrue when the number of attacking creatures exceeds the counters already sitting on the robot, so the build wants a board that grows faster than the reward it feeds: a token deck, a go-wide aggressive shell, anything that can present five attackers this turn after it presented three last turn. The trigger reads "whenever you attack," not whenever ED-E attacks, so the eyebot can stay home as a flier and still bank counters off whoever swings. Each counter is a delayed dividend, held against a single cash-out when you sacrifice it for cards, and that sacrifice is the tension the whole design rests on. The body is disposable by design (a 2/1 flier that dies to almost anything), which frees the card to be treated as a stored resource rather than a threat: you are not protecting an attacker, you are choosing the moment to spend a growing draw spell. The clock that matters is the board's expansion, not the robot's own survival. Cash in early and you refill a card or two; keep the counters climbing and the sacrifice becomes a burst refuel that only a committed go-wide deck can earn. The named ability is flavor scaffolding, but the reward underneath is a genuine payoff for attacking in numbers, banked and detonated on your terms.
