If you ask me Earth is the worst splinter to play against in Bronze, especially with Mylor. If I see that opponent is often playing Mylor, Unicorn Mustang, and Failed Summoner I try to focus on ranged damage. You can try to brute force with magic too but you need to have some heavy hitters. So I think that ranged is the answer in that case. Against Sneak and opportunity - try to put chicken or ooze in the last place. Against Snipe try to use Kelp Initiate on the second spot... or somewhere in the backline, depending on your other monsters.
