Summon a Megalorca token. If Overflow is active for you, summon 2 instead.
QI have a Prime Dragon Keeper on my field. If I summon 2 Megalorca tokens with this spell, how many times does Prime Dragon Keeper's "whenever another Dragoncraft follower that costs 3 play points or less is put onto your field" ability trigger?
AIt triggers 2 times.
QIf I play this spell when Overflow is active for me, but I already have 4 cards on my field, do I just summon one Megalorca token?
AYes, you do.
