Cletis, Baron of Nephalia

Protection from Spirits and Vampires

Other Humans you control have +1/+1, and Protection from Spirits and Vampires

Whenever another human you control dies, if it was dealt damage or targeted by a source your opponents control this turn, you get an experience counter.

The first Artifact spell you cast each turn costs {x} less to cast, where X is the number of experience counters you have.
