You need both to gain life and have something where decreasing the cost actually matters, and that just wont happen often enough for Will to be anything special She has solid base stats and comes with the ability to duplicate Enchantments in a set with lots of them
Id love to hear about your favorite creatures with flash
While I can see a need to put more Equipment in this particular deck, as theres only 16 core Equipment cards and drawing cards isnt always kind, its still a very well-rounded deck, with simple but powerful mechanics
Cards like Waterbender's Restoration, Extravagant Replication and Thassa, Deep-Dwelling repeatedly flickering your Aether Channeler and Riftwing Cloudskate gives you an incredible advantage because your opponents have to recast the same creature over and over (this is trickier in our era of powerful enters abilities, but still works)
While it only hits creatures and costs five mana, Sunfall has a few great things going for it
