How do we tank Trinisphere?

[Haksaw]

Just hazarding a guess, but I think Rack and Ruin is the best Wizards is going to give us until either Fifth Dawn, or the set after...

White now has the ability to destroy all Enchantments at instant speed.

Shatterstorm has been printed 2RR, destroy all artifacts at Sorcery speed.

I would not be surprised if they had a 2GG, destroy all artifacts at instant speed.

It'll bleed together with green's current role as the artifact hate-ness, while bringing conclusion to the "artifact block"

Speculation aside, you're going to have to settle for 3 cost removal...
