This deck focuses on +1/+1 counters to deal combat damage, search lands, draw cards, and a whole lot of utilities and buffs.
+1/+1 Engines:
Ordeals:
Ordeal of Nylea
and
Ordeal of Thassa
provide the +1/+1 counters and allow mana ramp and card draws.
Enchantments: [card]Hardened Scales[/card] doubles the counters and hastens the triggering of the Ordeals.
Outlast: well, only one creature with outlast - Tuskguard Captain, but it gives Trample to creatures with +1/+1 counters.
Spells:
Nature's Panoply
and
Solidarity of Heroes
gives instant speed +1/+1 counters - and with strive options - for combat offense and defense, also useful for triggering the ordeals
Untap Engine:
Prophet of Kruphix adds great support on this deck. It hastens the adding of +1/+1 counters and gives the deck great flexibility on the game.
Scourge of Skola Vale
can get really big when the prophet is in play.
Combat:
Heir of the Wilds
allows for a somewhat early defense and offense with it's deathtouch and ferocious abilities.
Jeskai Windscout
allows for a midrange offense; and it's Prowess ability is very likely to be triggered most of the time.
Icefeather Aven
is a good 2cmc for 2/2 with flying.
Burn and Control:
Crater's Claws
is a good old burn spell.
Icefeather Aven
has a useful return to hand morph ability to get rid of creatures in play.
Stubborn Denial is a cheap counterspell that is almost always sure to trigger its Ferocious ability because of the deck's big creatures.
