On top of these strategies, you can attack with your weenie creatures (now with deathtouch) and really put some pressure on opponents
A three-mana 1/1 that makes either a 1/1 deathtouch or gives your massive 12/12 Army a keyword that will let it kill creatures it was already going to kill is pretty underwhelming
A commander that reanimates a particular subset of creatures when it attacks isnt something new, with both Olivia, Crimson Bride and Drana, the Last Bloodchief doing exactly that
Additionally, its attached adventure copies an activated or triggered ability that player controls at instant speed for only two mana
However, thanks to how much you can ramp in Simic colors and with Nadu's ability, you will likely always have the mana to re-cast it , so don't worry if it gets targeted for removal
Maybe they could have had something by tying the landfall theme to the crystals
