Teamwork is the last new mechanic from the sets, and acts almost exactly like Convoke! This one cares about Power instead of the number of creatures. Pay the Teamwork cost to upgrade your spell for a small bonus! #MarvelXMTG #TinyLeadersReborn

Power-Up is another mechanic brought to us by the Marvel set. It's basically Kicker, but isn't everything basically Kicker or horsemanship? You can play the Power-up cost at any time, and it is reduced if you pay it on the same turn the creature entered, but only once #MarvelXMTG #TinyLeadersReborn
