Francisco, Fowl Marauder

A 0/1 flier that explicitly can't block is a strange creature to build around, and that self-imposed helplessness is the whole design logic: this is not a body, it is a trigger controller wearing feathers. The explore payoff keys off any Pirate you control connecting with a player, not off Francisco himself, but the trigger reads "one or more Pirates," so a full alpha strike still yields a single explore per player damaged, not one per attacker. That framing matters: the engine rewards dealing damage often rather than dumping an overwhelming board once, since each separate damage event to a player (including first-strike and regular combat damage in the same combat) is worth its own look at the top of your library. The Partner clause is where the design earns its keep: pairing it with a second partner bolts this explore engine onto another color's threat suite without abandoning the deck's core, and it invites the classic partner-pair economy of splitting one role (aggression, ramp, protection) from the other (grinding value). What keeps a two-mana repeatable card-selection engine in check is that Francisco contributes nothing on offense or defense by himself; he is inert until a functioning Pirate assault is already underway, so the value spigot only opens once the attack does, not merely because he stuck around.
