Pyre Route, kill them before they kill you
Pyre's ability is +1 speed to all monsters you control
Making you hit first and possible dodge on melee and range attacks
Beginning with your free cards, my suggestion especially on low mana matches
When you can rent (minimal DEC needed)
First to work on is, make your earnings +10% with ALPHA and PROMO CARDS
Notable ALPHA/PROMOS rental monsters
3 mana 1 range + snipe, very cheap rent
3 mana -1 heart to enemy team, very cheap rent
2 mana 1 melee + sneak, very cheap rent
4 mana 5 health + heal, your tank, optional rent for +10% gains
Second, rent this to for neutral support
Slows down your enemies for 1 mana
Third, complete the team with any of this
3 mana 2 melee +opportunity, targets the lowest health monster
2 mana 1 melee +opportunity, targets the lowest health monster
Remember, the aim of this set up is "kill before getting killed"
Mix and match this cards and see where you win the most
