The Wandering Minstrel | Legendary Creature | Human Bard | Lands you control enter untapped.
The Minstrel's Ballad — At the beginning of combat on your turn, if you control five or more Towns, create a 2/2 Elemental creature token that's all colors.
{3}{W}{U}{B}{R}{G}: Other creatures you control get +X/+X until end of turn, where X is the number of Towns you control. | Thanh Tuấn

Jenova, Ancient Calamity | Legendary Creature | Alien | At the beginning of combat on your turn, put a number of +1/+1 counters equal to Jenova's power on up to one other target creature. That creature becomes a Mutant in addition to its other types.
Whenever a Mutant you control dies during your turn, you draw cards equal to its power. | Ignatius Budi

Sin, Spira's Punishment | Legendary Creature | Leviathan Avatar | Flying
Whenever Sin enters or attacks, exile a permanent card from your graveyard at random, then create a tapped token that's a copy of that card. If the exiled card is a land card, repeat this process. | John Tedrick
