In the case of attractions, it turns out that stapling them onto a competent Izzet spellslinger commander is a surprisingly viable way to pull that off
Valley Floodcaller, on the other hand, is a 2/2 creature with flash that gives all your noncreature spells flash while its on the battlefield
From flashing out blocks to EOT and then attacking with an army they weren't expecting, you can abuse, and then flashing out gives your foes less time to answer card draw like Phyrexian Arena on their turn or combo pieces and cast them all at once
It really does an awful lot and I am excited to test it out and see if it lives up to expectation
Golgari Self-Mill, in particular, has a really rough matchup here
