Most combat-manipulation creatures pull one lever: force a creature to attack, or hold one back. This Minotaur does both, every combat, on every player's turn. The lure half (forcing an attacker or blocker into a fight it would rather avoid) is an old red effect, going back to taunt creatures that drag a defender into the open. The pacify half (locking a creature out of the combat step entirely) is the white tradition of pacification. Stapling them together on a recurring trigger turns the body into a combat referee: it decides which of the opponent's creatures matters this turn and which one is benched, and it can point at either side of the table, so it can smooth your own attacks as readily as it warps theirs. The "up to one" wording is what stops it short of a hard lock: each effect touches a single creature, so a board with multiple relevant blockers can absorb the redirection rather than collapse to it. The 5/5 body is almost incidental to what the card is for; it is a control valve on the combat phase, repeatable as long as it survives, and the recurring "at the beginning of each combat" timing is what separates it from the one-shot tricks that do either half for less mana. It asks to be built around boards where steering a single creature each turn is enough to break a stall open.
