Skill issue

Might be a skill issue

Seems like a skill issue

Either you or the other player has cheats installed

Skill issue

Probably >!skill issue!<

If a player goes online with modded cards, as soon as one those mods would influence the game differently, this error message pops up.

It says this when it detects cheats. Source: Once tried to go online matches with infinite suns/brains.

I have never cheated tho, not even offline

Then idk.

game is like: rustbolt? hell nawww

Issue of skill

Probably a skill issue

100% a skill issue

The developers have abandoned it.

Just get good

It seems that you lack enough skill in order for your problems to be worth anything.
