Lands you control have "{T}: Refill your mug with a festive drink." (If you don't have a mug, go grab a mug! It's the holidays!)
At the beginning of combat on your turn, if you have a drink 'stache, put two +1/+1 counters on each creature you control.

Blend dingus egg yolks, milk, Eldraine spice blend, Muragandan vanilla, and absolutely nothing else.
