A general list of strategies I've found in the game:
Defensive decks all follow the same trope, Life Separation. There are several ways to do this:
2) Life Gain
3) Damage Reduction/SoA/SoB
Any combination of the three can produce the desired results. The general strategy of a defensive deck is just controlling the flow of damage, by reducing card's damage through DR or SoA where appropriate, and landing your damage where it counts (often by denying a high damage card from your opponent). Defensive decks win through maintaining a good amount of life separation. Some defensive decks can with the round on the first turn with a single furious card, such as Pussycats
KO decks contain a large amount of cards that can dish out 2 hit KOs with one another. While the strategy itself seems straightforward the tricky aspect of the deck is making your opponent predict the KO. Landing an early Emestath in a La Junta
deck, for instance, forces your opponent to be on the look out for a second hit for the rest of the game.
Finally, probably the most common type of deck in ELO
is a balanced deck. The goal of a balanced deck is flexibility. A balanced deck can be played both defensively or offensively depending on the strategy chosen by the opponent or the specific cards drawn. It can with through life separation or KO. These decks contain cards of both the offensive and defensive variety. These decks tend to go furthest in ELO
due to their adaptability.
