The only deck I actually enjoy since a very long time, went 36-21 (63% wr) with it, but I made some misplays in the first few games cuz I was still learning it hence the smaller wr. Eater is definitely replacable by glide if you don’t see mages, you can beat mages without eater too but it’s much easier with it. Best mulligans are sigil, paraglide and illidari studies, they are always keeps.
