Here's what we have:
Creatures
I really wanted Polyraptor in this deck (for what I hope are obvious reasons), but it was just too mana-intensive. Something I've noticed is that it feels bad any time I draw a Goblin Bombardment while I already have one out, and the same is true for Pyrohemia (though that one is less so if I'm out of creatures - that said, that doesn't happen all that often, so...). I gave it some consideration, and I think I could probably take out 2 of each without damaging the effectiveness of the deck, and Raging Regisaur could be slotted in, in their steads? Sun-Crowned Hunters is really good, here, but unfortunately, anything over 5 mana is too expensive to be able to use consistently. There are some other things that have caught my eye, such as Yidaro, Wandering Monster, but I think Regisaur is the best option for keeping things efficient, consistent, and streamlined.
Thoughts?
