Slinn Voda and Whelming Wave are board wipes that bounce everything but the four creatures types we're using back to their owners' hands, while Deepchannel Mentor and Serpent of Yawning Depths make them unblockable to any unfortunate leftovers who remained after the wipe
Making every artifact you cast become two is perfect with cards like Urza, Lord High Artificer, Nettlecyst, or sacrifice outlets like Phyrexian Altar
It's a shame because several of them are excellent characters well deserving of their own cards and what we got instead was just awfully bland
Its a bit like a really strange group hug card, and its one of the most entertaining commanders to build around
Sapphire and Steel is a competitive ink combination, but few of the cards in this starter deck see top-level play
This means I had to dig to find a lot of staple effects ramp, removal, and card draw on Legendary cards, most of which are permanents because there are barely any Instants or Sorceries
