Grypolyth is pretty decent. It depends really what you think bets fits your team but I think grypolyth is better. You already have phourex which is probably a better version of grylenekyn
Go for Grypolyth. It’s a decent endgame creature and a great counter to Testa, which you’ll see more of the higher up you go.
Grylenken is great for the mid arenas and legendary tourneys but Grypolyth is far much more relevant in the meta and better in the long term run
So yeah get Grypolyth
If you look at grylenken. It’s basically useless. Not many people use it. It’s really got nothing going for it.
With grypolyth it’s a different story. A decent amount of people use it. It can counter and be countered.
Grylenken has honestly been forgotten.
It’s actually really good
Where is it good? Not for the Library
Well, it can be useful in high up against the right matchups. Ask @koffibun
Thanks I will save for grypolyth
