Being able to stack your hand with your best equip options and then boost all your creatures as a side-effect of stacking them on Kellen makes this card an auto-include for any red/white deck with an equip focus
The extra spicy tech in that deck is how Thing in the Ice is going to come down anyway, and live through the Suns
On the other hand, hit a hot streak, and you'll be the biggest threat at the table, so it really is a case of fate deciding what kind of game you're going to play
It can lead to confusion during play
Since this is both a sacrifice outlet and puts a land into play, all you need is a card that makes tokens on landfall, like Scute Swarm or Sporemound, an Intruder Alarm or Retreat to Coralhelm for untapping, and a Karoo land to draw your entire deck and get enough landfall triggers to take out the table with effects like Retreat to Hagra or Ruin Crab
Players should expect MAT card prices to drop slightly after release
