How to read the letters
S and A are units that a meta note or a mode guide singles out for Infinite, raids, or economy. B and C are units those same sources still recommend for a role, with less detail. Trait ranks and shiny status can move a unit more than the letter. Story and Infinite do not share one best team.
S tier
Player decision Use it as the long-run carry once a farm unit can pay for its upgrades. Save Trait Crystals for this rarity: Secret rolls cost 5.
Player decision A raid and Infinite piece when you already own the unlock. Fear does not replace a farm unit.
Player decision Bring it to raids when the freeze covers the path you are losing. It is an Ancient banner unit, not a 50 Gem target.
Player decision Craft Fire Dragon Soul when Flame Dragon King is already your area unit. Do not start a second project beside it.
Player decision Pair with a slow such as Ice Dragon. It is the wrong only-unit for spread waves.
Player decision A general damage slot, not a replacement for area clear or farm.
A tier
Player decision Keep it if you pull it. Evolve only after the Gold crafts you already rely on are done, because this evolution's Gold cost was not in the item extract.
Player decision A mid-budget evolution compared with the 26,500 and 28,000 Gold crafts.
Player decision Evolve Donut Warrior if you already use it for early economy and want the slow. The farm board still lists the base unit.
Player decision Good main damage while you build a Secret carry. Confirm the rarity badge in game before you spend 5 versus 3 Trait Crystals.
Player decision Place it on a corner that sees a long path. Evolve to Flame Dragon God when that area unit is still in the team.
Player decision Evolve if Carp is already placed. The shortlist does not say whether the base or Prime form is the meta piece.
Player decision Add it when leaks are from speed, not from a lack of damage.
B tier
Player decision A reasonable early Mythic evolution because the Gold line is low. Still read the in-game kit before you assume it is area damage.
Player decision Keep and test. Evolve after the crafts that have a known cost if Gold is tight.
Player decision Use it if the kit fits the wave you are losing. Do not wait on an evolution name that was never printed.
Player decision A control or utility slot beside The Gamer. The 28,000 Gold craft is a late purchase.
C tier
Player decision Use whichever ice-control unit you own. Do not sell Admiral of Ice just because a later page uses another name.
Player decision A filler control piece, not a craft target.
