>>112041384you can get certain cards by playing the singleplayer mode (some you are guaranteed to get from singleplayer, like cyborg kenny). the rest you can get in the free packs (you get one every four hours, and you can have up to two "waiting" to be opened at once) or the pvp packs. the higher the pvp arena you are in, the higher chance you have of getting rarer/better cards. you can even get legendary cards without paying; i got stan of many moons the other night from an arena 5 pvp pack. that said, it took me a while of playing to get that card.
its kind of grindy, but not particularly time consuming; i can destroy enough phones to get the pvp pack in less than 20 minutes, and i'm not exactly good at the game.
my preferred strategy is to use the coon card, because every other superhero-themed card you have on the field buffs his attack, and it stacks. depending on what cards the game draws for me in the beginning, i will usually open with the coon and mosquito - mosquito is good to use with coon because he spawns a mosquito swarm which ALSO counts as a superhero ally. which means that playing mosquito after coon will give coon two attack buffs. after mosquito, i usually follow up with either toolshed or human kite, preferably human kite because his special power gives all allies in a certain radius invulnerability for a few seconds.
coon can get ridiculously stacked; if he's upgraded enough and you have enough superheroes on the field he can have over +100 attack.
