At that point I would feel like this card wants to both promote active mitigation and reduce interaction. They aren't mutually exclusive but that does feel like a contrary pull.
Call me greedy but I would want this card in with haste. I see people playing this, passing, and the opponent getting a value chain that ends with a removal spell
Interesting drawback/Plankton ability I have not yet seen - usually subsets are made more expensive (by color/type) or sometimes those targeting a creature cheaper. Just giving handouts to opponents for raw size is not a thing (yet).
Originally I wanted to call the mechanic "blessed" or "blessing" but I like the idea to keep it open for resilient monsters, but the word stays in the card's name.
Yes, that's totem armor. Keyword in reminder text would make this a two-liner.
I like it. Perhaps 'too fun' at uncommon? Tbh it seems most cards can be at uncommon these days - wraths and such aside. That 'rare only' section has been dwindling over the years.
I could see the desire to really push this powerwise. You know, it could cost or just and have "plus 1" at the end of that ability.
How come people keep walking into this wall? How do they not notice it? It looks rather monumental to me.

Giving it hexproof might be a better option than haste, if that's what you're worried about

(Something is monumental if its converted mana cost, power or toughness is 6 or more.)
