Puregrove Branchbonder

Primal {1}{g}{g}{g} (You may cast this spell for its primal cost. Spend only mana produced by basic lands to pay that cost.)
When Puregrove Branchbonder enters the battlefield, you may put a +1/+1 counter on another target creature. If its primal cost was paid, put three +1/+1 counters on that creature instead.
