Ingenious Infiltrator text: "Whenever a ninja you control deals combat damage to a player, draw a card."

You only ever draw 1 card no matter how many ninjas deal combat damage that turn.

Toski, bearer of secrets text: "Whenever a creature you control deals combat damage to a player, draw a card."

You draw as many cards as attacking creatures dealt damage. Why is that? It is exactly the same text but replace the creatures with ninjas.

Either this is a bug or Ingenious Infiltrator should have a, "activates only once per turn". Text at the end.
