ABOUT AXIE: ORIGIN

Axie Infinity: Origin (Battles V3) have brand new interfaces, game mechanics, art, special effects, storylines, and an expansive onboarding experience. 
Axies will execute their attacks immediately when cards are played. Instead of choosing their cards at the beginning of a round, in Axie Origin, players will take sequential turns to use their cards. This is expected to make the Axie Infinity gameplay more fast-paced and engaging.

Additionally, there are many new mechanics around retaining and acquiring energy/cards since unused cards will no longer carry over across turns.

Axie Infinity: Origin also released various new cards for the Tail, Back, Mouth, Horn, Eye and Ear, although some of these are just upgrades or adjustments from their previous versions in order to fit the new game mechanics. This is also the first time that an Eye and Ear part will have their own cards.
