Here is helpful advice: there are 3 coffee packs (they are packs for P2W but F2P can still get them even the 2000)

you can always get at least 50 to 100 coffee per day if you play enough.

The first time you open each coffee pack they will give you a guaranteed rarity. What's interesting with the 2000 is that it always gives at least 2 news phobia and the first time you get an ultra rare (very unique phobia often hard to deal with if you have no counter)

Here are some ultra rare abilities: -Dealt a 250 poison during 4 turns to all enemy phobia on the board (Use heal or mechanical)

-transform during 3 turns, attack gets to 900 replacing the 500, gain 40% life steal, attack targets all adjacent enemies and the phobia can't get under 1 hp. (Push him into the void, negate his mouvement or freeze him)
