Bittertide hydra is just solid and really well statted, 5 mana for 8/8 stats is really strong on board, you can maybe sub in Cobalt Scalebanes to fill the 5 mana slot.

It’s basically big priest but with malygos to help close games or clear the board. it might be a good choice if a priest meta develops as there are a loot of hard to remove targets for priest.
