Theres an argument that these are better in the 99 than as the commanders of a dragon deck because they offer card advantage when they ETB and fetch the other one from your library
Its no surprise this Arachnogenesis sees heavy play in Commander
Great for TCGs like MTG, Pokmon, Lorcana, & Flesh and Blood
Because of that, for my article this week we'll be taking a look at various Grixis builds that all went 5-0 on MTGO , so that you can find your perfect Grixis deck to play
Playing Imduk and Hieratic Seal is also a good option
Also, if its countered, destroyed, discarded, or milled, youll be able to put it right back into your library and possibly get it again
