I think the only good competitor against steemmonsters is gods unchained on Eth... and to be 100% honest, they seem to be getting the upper hand, they just added one of the former MTG arena game directors and those guys know all the ins and outs of marketing and adoption of card games.

Let's wait and see... if we can get some new features, more cards and maybe a leasing market up I think gods unchained ppl would start sweating rly hard, there is enough space for both games, but the number 1 spot should be ours!
