Two main issues: 1.) This game tried to be 5+ different genres at once (Candy Crush, gotcha heroes, generic kingdom builder...) and excels at none of them. The idea is interesting, but it all falls apart in execution. 2.) Devs are BEYOND stingy. Do not expect to earn Summons as f2p. The gem cost is high, summon items are gated to ~5 per month in the shop (half of a x10 summon), and the only other way to get them is by spending over $20. Contest rewards don't even give out 1/4th the summon cost.
