Raul, Trouble Shooter

Milling as a resource engine rather than a wincon: that inversion is what makes this design interesting. Most mill in these colors is a clock aimed at the opponent's library, but here the tap ability points at every player, yourself included, and the payoff is that the cards you bin become castable that same turn (you still pay for them; the graveyard just becomes an extension of your hand). The 1/4 body is deliberately defensive, a wall that survives to keep tapping, because the whole design wants you to grind the same activation across many turns rather than race. The once-per-turn cast clause is the release valve that stops the engine from running away: you can capitalize on only a single milled card per turn, so raw mill volume never snowballs into a barrage of extra plays. It rewards deliberate self-mill built around cheap spells you can immediately deploy and cards that want to be in the graveyard anyway, and it turns the top of your own library into a rolling, one-shot pseudo-hand you have to spend before it decays back into the yard. The tension is that the same tap feeds every rival's graveyard too, so the engine leans toward builds that either don't care what an opponent digs up or actively want to fill all bins. A slow, self-referential value machine wearing the costume of a mill card.
