This is possibly the best thing thats been done for Commander players for a long time, but it helps out everyone else too
Like River Kelpie, you can combo off with this alongside Ashnod's Altar and Spark Double, so keep that in mind, but I think you're happy to use this to protect your game plan or disrupt your opponents'
Tameshi provides an added incentive for playing bounce spells as she allows you to draw a card once per turn as long as something is bounced
Most of these cards will dip down into bulk territory before bouncing back up, so the set may feel lackluster for a while, but I am very high on M15s long term prospects
The inherent flexibility of energy means you dont need to think as much in terms of specific card combinations you just need your draw to hit a certain total threshold of energy, which you can number-crunch with a similar kind of consistency to manabases
This 5-drop flash, flying 4/3 will let you flash them out, and sorceries too
