Or Seismic Stomp.
Akroan Hoplite should be Firefist Striker.
not necessarily.
firefist striker should be in the list but not as a replacement for hoplite. he actually fits the scheme very well. i run 4 of each, and no mastiffs. you should try to replace the legion loyalists with a white one drop, this will allow you to streamline your mana base more (consider
soldier of the pantheon). speaking of which, from experience i can tell you that running 20 lands will stop you from hitting your four drop as often as you'd like. cut the
chained to the rocks, its good but 9 mountains isnt enough to warrant it as a 4 of. generally speaking you want around half your deck to be creatures to have battalion pay off. i run 23 lands, 3 lightning strikes, four boros charms, and 30 creatures in my deck.
