Nice card ideas,combining both Evoltiles and Evolsaurs to make something a bit new that also helps build up a field for the Xyz summoning of the Evolzars. The Field spell seems a bit much but maybe that's just me, I say this only because of the first effect where they can't be targeted could be a hassle to work around, then again that might be what this effect is for:
