No creature Relic/Spell deck (3 victory conditions)

This is my first attempt at a deck, so any input is appreciated.

I love Eternal but I'm bored by the creature spam meta, so I decided to try making a no creature deck. After many versions, this one is my most successful.

There are two rules to this deck:
1. Survive early game
2. Build towards one of the four victory conditions

You have 4 victory conditions:
1. Channel the Tempest them to death. Very straight forward.
2. Mill them to death with solitude. Use excavate to get another solitude.
3. Azindel's Gift -> The Last Word. I wouldn't try using The Last Word without first triggering Azindel's Gift OR the other player having 0 cards in their hand.
4. Hatecleaver + Stronghold's Visage build up.

This deck is weak to a deck full of aegis creatures + weapons.
