AI-assisted browser playtest from Worst In World: I checked the opening three turns in desktop Chrome via the English page → Play free → Quick match.
The green-card/red-target cues and changing top instruction worked well. I played Llavera del galpón, ended the turn, used Bochazo on Mulita curiosa, then attacked the opposing hero. The guard disappeared and the hero went from 24 to 23, so that first spell-to-attack sequence was easy to follow without the deck-selection menu.
One guide gap: Mulita curiosa's enlarged card says “Guard (cannot attack),” but the Help guide lists Taunt and other keywords without a Guard entry. Adding Guard there, with a brief distinction from Taunt, would help a newcomer understand whether it only prevents that unit attacking or also restricts enemy targets.
This covers the opening actions and guide, not a completed match or physical-phone test, so I don't have a balance verdict yet.
Update for the browser-game exchange you offered: our Pocket Wordplay draft is now playable on itch: https://worstinworld.itch.io/pocket-wordplay?secret=olgZJp9DeJvnWiqnQkoRaKeqk
It is a tiny AI-assisted satire toy with two free samples and no login. Nothing in the pocket edition is published; the optional full game has public edits and optional purchases. If you try it, the useful question is whether making the first sentence makes you want to remix a second one.
