with the current ark roster released at the moment…
if the stun user knows the combo really well, there is no counter its a locked win from the start 100%, the moment you you make the first move the match is already lost(unless you play a stun team too then it’s a matter of who gets the first move). if you meet one of these, usually marked with 3 stun wind arks in the initial 3 line up or 2 wind stun arks and 1 ark with retreat, just make the first move, put your phone down and get a snack or watch something on tv, because it’s already game over.
However fortunately a lot of players still unfamiliar with all the arks in the game, so there is a chance to beat such team if you get a player still learning the combo. barricadus, metallodius, and moss golem serve just as time stallers to the inevitable. Arks with scramble will help too. Stick all these arks along with making sure almost all the arks in your line up have beastbane, so when charcalynx messes up, you 1 hit charcalynx. By then however charcalynx has probably already wiped out more than half you team if there is actually a window of opportunity to take out charcalynx in a single turn,
the idea is to fill up as many anti stun arks in the beginning of the team as possible so there are too many for the stun user counter everyone.
doing this however will weaken your team against regular non stun teams.
and if the stun charcalynx team incorporates super arks like minespider, vegitiger, and other egg only arks at the end of the line up, you don’t have a chance, even if you break the charcalynx combo.
the best counter is just to wait for the update, when stun is fixed and pvp returns to normal.
