Medics and Rot Tossers are the really good choice. But you can't underestimate Emhyr's value defensively. He doesn't have to bounce a card, he can simply remove a card from the board. For example:
- Iris
- Lord of Undvik
- Cow Carcass
- Fireball Trap
- Sabrina Glevissig
- Spectral Whale
- Fake Ciri
