My top tips-
1.setup strong early game control in the center of the map and then play defensively. Wait for your opponent to make a misplay by developing his phobie to deep, then punish him by combo killing his phobie with your phobies.
2.multiple weak phobies > one strong phobie. This is because having multuple units allows for you to spreadout the damage and it allows you to combo kill enemy phobies.
3.If your opponent takes early stress point control, then summon range phobies to poke him off those points. After this slowly retake map control.
4.Develop your highest lvl phobies always.The raw stats of leveled phobies are all that it takes sometimes to win the game. For example your lvl 8-9 Jar cannon cant get oneshot by a lvl 5- 6 murderwing’s ability and that puts your opponent in a though spot where has to make less optimal plays.
