Dies to Removal

If hippy isn't good, why would a less reliable version of him be good

You don't need that much discard honestly, between hymn+therapy you should strip their hand very quickly and turns additional copies into dead cards, your deck looks like it wants to grind it out as well meaning your going to draw more discard when you need to answer their threats

Zoo isn't a deck anymore and I wouldn't worry about it frankly

If you consider your dudes expendable, innocent blood seems better than tragic slip, it kills tnn and mongoose

This deck seems like it has trouble with resolved permanents

Would add some combination of Lilly's/removal cutting some combination of iok/hymn
