Innkeeper's Talent provides three fantastic effects split between its three tiers: for two mana you get a +1/+1 counter on one of your creatures each time you enter the combat phase, then, for one more, all of your permanents with counters get ward 1, and finally, for four more mana you'll double the number of counters you get on every permanent you control
Best MDFC Payoffs MDFCs dont have a lot of cards that work specifically with them, at least since the rules around cascade were tweaked
Entering the battlefield with two additional bodies is slight overkill for Celebration triggers, so this card is most efficient for Rat sacrifice builds and might get bulked up into a semi-evasive finisher, something every "aristocrat" deck needs
The same is true for first strike, double strike, deathtouch, hexproof, indestructible, lifelink, menace, reach, trample, and vigilance
