Continuous effects that affect the costs of spells or abilities are applied according to the order specified in rule 601.2f
You put just one +1/+1 counter on Littjara Kinseekers and scry 1, no matter how many extra trios of creatures that share a creature type you control
The set has dozens of high-tier Constructed playables to offer, from the flashy mythic rare Dragon to the typical Draft removal spells
The less human version is Tovolar, Midnight Scourge, whos a 4/4 with the same card draw ability, but this time around you can pay X, one red, and one green, to give a Wolf or Werewolf you control +x/+0 and trample until the end of the turn, which is a great way to finish someone off
The card is pretty low powered but it does help you stay in the game early when you are most vulnerable to other cheap creature decks
