This reminds me of Kona, Rescue Beastie in terms of the risk/reward involved, but a little bit weaker overall
With that in mind, it is lower on the list
Players enjoy the decks charming squirrel theme, calling it both fun and surprisingly strong in token strategies
The thing is, the turn still ends with these effects, so something that simply lasts until the end of turn will still act appropriately
It is generally better than Infest and better than Dismember just in terms of effect (very little is more effective than Dismember at 1 mana!)
Surveilling 2 on the plus ability of a planeswalker is strong, even if it doesnt give you cards, and you can get card advantage by making your opponents discard cards while feeding your graveyard synergies
