mtg kaldheim god cards Valki, of Lies SHOWCASE FOIL 308 NM Kaldheim Rare: Reidane & Valkmira

All by himself, it seems

In fact, this Elf makes sure players can't draw cards for any reason, no matter what the rules say

Thats some massive upside in heavy counters decks, and this is already a fairly aggressive survival creature on its own

The activation is cheap, but you'll have to re-equip whatever you unattach, so Akiri really wants to be surrounded by some cheap equipment

For blue, it comes from the ability to draw cards, and colorless cards and land have the tendency to be especially dominant because they can theoretically fit into any deck (and the opportunity cost of playing lands is significantly lower than that of other card types)
