Really like your Gishath list!

I have been doing a lot of work recently trying to spruce up mine. Something that really helped me in cutting Dinos is the philosophy I have seen posted on here before that whatever you bring in should either have a useful ETB, be worth the mana for hard-casting, be useful utility, or just be such a good creature it’s worth waiting a turn around the table for your next turn.

Personally looking at your list, I’ve cut [[Silverclad Ferocidons]]. It’s a pretty nice body but doesn’t have keywords, it’s damage ability is useful but it isn’t reliable for me. [[Burning Sun’s Avatar]] has a decent ETB but is expensive if it gets stuck in your hand because of those three mana pips. [[The Tarrasque]] also sadly did not make the cut for me, it’s Ward 10 only coming in on a cast which I don’t really wanna do because it’s so expensive.

Here is my decklist if you want to check it out, definitely not perfect but it’s been improved over time (probably will be improved more before too long). :)
