I like this a lot but I don't know what deck wants it.

Love the art, I really should make a librarian/archivist Vorthos deck one of these days. The abilities are great, sad that they only trigger once a turn but the triggers themselves are more powerful than expected.

This one seems kinda crazy to me

Elvish Archivist - 1G
Creature - Elf Artificer (Rare)
Whenever one or more artifacts enter the battlefield under your control, put two +1/+1 counters on Elvish Archivist. This ability triggers only once each turn.
Whenever one or more enchantments enter the battlefield under your control, draw a card. This ability triggers only once each turn.
