Kavu Monarch

The Kavu were a synthetic species, a tribe invented to give a domain-and-tribe block a creature type that could span every color at once, and this is the lord that holds them together. It works in two motions. The first hands trample to every Kavu, the Monarch included, so a board of midrange beaters stops getting walled by chump blockers and the lord itself arrives with its own evasion. The second is a growth engine: each fresh Kavu fattens the Monarch with a +1/+1 counter, and because the trigger reads "another Kavu" without regard to controller, it climbs off your opponent's Kavu too. That second clause does more than a flat anthem ever could, scaling with how many Kavu you actually deploy rather than rewarding mere presence, so the math tilts harder the deeper into the type you commit. The vulnerability is structural. As a 3/3 for with no protection, it dies to the same removal that answers any four-drop, and every counter you banked walks off with it, since the counters live on the lord rather than on the team. It belongs to an older school of tribal payoff, where the anthem and the snowball were stacked on one body and you were asked to assemble the board first, trusting the counters to make the combat math lopsided once the Kavu were already down.
