Much like Ghalta, Stampede Tyrant, Gishath allows you to put any number of Dinosaur creature cards onto the battlefield, but, improving on the formers ability, you can dig through the top X cards of your library to get them (based on the amount of combat damage it dealt)
If youre specifically looking for the best colorless cards MTG has to offer thatll let you make high-level plays via easier setups, then youve just found one of the highest-tier ones there are
If you tire of treasure, or you dont want a Planeswalker Commander, then Shanid is another great Mardu option
