Helms incredibly expensive to cast and equip, but who am I to step between a card and its loyal fanbase
You're paying 4B to start with, and then you also have to sacrifice a creature with high power to make X a relevant value
What Squirreled Away does best is teach a new player about creature synergy and strategy
Then the -2, which can be done twice with the starting loyalty of five, will make two 1/1 Nightmare tokens that will grow with +1/+1 counters permanently if you exiled a card this turn
I like it also because it flies, helping to trigger anything from Chivalric Alliance to strong equipment triggers, with less risk
As an uninkable card with a cost of nine, there's an inherent risk in keeping this in-hand, but any deck that's designed to take a beating can quickly increase its viability
