Tahm Kench and Mikael's Crucible - Fast Food

I made a video on the topic, here's a link.

I think this has some stupid dumb potential. With just those two items, you have 225% Mana Regen converted onto the 150% Health Regen for a 375% Health Regen. Needless to say your sustain should be solid. You'd have armor and magic resistance to boot.

Is the combo too hard to pull off? I think not. Will it have value? Absolutely. Not to mention you still have a Mikael's Crucible to protect your ADC. Oh the options!

Keep in mind that taking those two items can still lead to a build with high survivability and utility. One example would be:

Talisman of Ascension Knight's Vow Mikael's Crucible Spirit Visage Warmog's Armor Boots of Swiftness (boots are flexible)

This would provide a substantial amount of armor, magic resistance, health, and health regeneration. You would also have quite a bit of utility and max cooldown reduction.

Please discuss, I would love some input!
