Raging Regisaur

The open target line makes this design work: most attack-triggered damage in Gruul points its ping at the defending player or restricts it to a blocker, but here the damage can go anywhere, which turns a routine swing into a flexible burn spell that resolves before combat is even joined. The timing does the heavy lifting. The trigger fires on attack declaration, ahead of the blocking step, so a one-toughness creature that would otherwise block and trade dies to the ping first: the attack lands into a board that has already lost a defender. Point it at a planeswalker instead and you shave a loyalty a turn without committing to the assault; point it upstairs and it is incidental reach the deck did not have to pay extra for. It sits in the lineage of creatures that convert each swing into repeatable incremental burn, the kind that reward keeping a beater alive and attacking rather than assembling a fragile combo around it. Extra combats or additional attack steps stack the pings, but the bare card needs no scaffolding to earn its slot. The body does not dodge much (destroy and exile removal kill it as easily as they kill anything), but four power and the ping together demand a prompt answer, and every turn the answer is late is another point of damage aimed wherever it hurts most.
