Initiate's Companion

A 3/1 for two mana that hits like an ordinary green beater but carries a small combat-triggered engine, untapping a creature or land each time it connects with a player. That single target field is where the value hides. Point it at a land and the swing funds a turn's worth of instant-speed interaction; point it at a creature and it becomes a pseudo-vigilance enabler, letting a blocker attack and stay back, or resetting an attacker to fire off a tap ability again. The fragile body is the cost of admission: it trades into almost anything, but it costs little and hits hard enough that the pilot wants to push it through unblocked, which is precisely the moment the untap resolves. So it rewards a board built to be untapped (mana sinks, tap-to-activate creatures, anything hoping to ramp into a haymaker on the same turn it attacks) and offers nothing to a board with no such target waiting. It sits in a long line of green two-drops that smuggle a modest engine onto an aggressive curve, asking the pilot to find the line where one connection frees the resource that closes the turn.
