Praise Helix!!
Or not. Overall this Omastar is not really worthy of Lord Helix status. I appreciate and actually like all the suggestions above for things it combos with, but tbh it's not worth it to get out what is basically a stage 2 with an un-searchable basic form (except by Skyla, which uses your supporter). I mean streaming Tyrunts is admirable (Tyrantrum is probably the best restored Pokémon we've ever gotten, competing with Archeops) but realize you have to get Omastar out first... and even then you only get one per turn (unlike, say, Lifesplosion).
Granted, if it has amazing synergy with Kabutops, gets its own fossil support (like Fossil Researcher, a fossil stadium, fossil energy or items, or if Helix fossil is as amazing as "put this card down onto your bench then put Omanyte from your deck directly on top of it") then maybe it will work. I'm a proponent of "every card should be viable at least for fun" so my fingers are crossed for our friend Helix!
PS: Love the art too!
