Wildcard

Wildcard is a PvP collectible-card-based MOBA (multiplayer online battle arena) developed by Playful Studios and currently in Early Access on Steam. Players pick Champions, assemble decks of Summon creature cards, and compete in real-time strategic arena battles where deck-building matters as much as mechanical skill. The game ships collectible cosmetics (Wildpass, Flair, Wildfile) with a web3 angle — the Wildpass is a Polygon NFT collection tradeable on Magic Eden — and is backed as a portfolio company of the crypto venture firm Paradigm. Its backend gaming services are built on Beamable and Unreal Engine. No first-party public developer API, SDK, or documentation portal is published; this profile is a company/lead record in the API Evangelist network. Sector: gaming.

Wildcard is profiled on the APIs.io network. Tagged areas include Company, Gaming, MOBA, Card Game, and Web3.

Wildcard’s developer surface includes engineering blog, support, signup flow, and 2 more developer resources.
