I theory crafted a handbuff ST deck with the new cards. Here are my thoughts.

Syanna, Unicorn, offering, and Fortune teller are simply replacements. They need to be swapped out for new cards.

1. Devotion might actually work in decks favor
2. There is no need to put all of your boosts into one card anymore
3. Vrihedd Saboteur might actually see play
4. There are multiple easy way to boost Filav, so he might actually work.
5. Nature's gift might work better than invigorate
6. Can't decide if elven wardancer or watcher of the valley is better. Wardancer is 6 for 4 but watcher has higher potential.
7. Still deck can benefit from being able to draw the card you want.
