Legendary Creature — Elf Warrior
At the beginning of combat on your turn, you may pay XX. When you do, distribute X +1/+1 counters among any number of target Elves you control.
Straight out of the leaks Magic's Taiwanese Instagram account, more Elfball. Oh, and the FTV:20 Fyndhorn Elves art makes it to a nonfoil printing (and a foil printing that's worth less than its current $21 price tag).
Some nice reprints, and as others have said, the Fyndhorn Elves reprint is actually pretty decent. It was fast becoming a $3 common. Farhaven Elf was sitting at ~$2 too. As for the commander itself, it's easy to slot into an Elves tribal deck as a mana dump.
