Taxing non-creature spells doesn't hurt us much at all (our only non-creatures are Ajani, which is still powerful at five mana, and Conclave Tribunal, which we can convoke into play on the cheap even with Thalia, Guardian of Thraben on the battlefield)
Those who hear its roar perish
Teysa Karlov neatly combines buffing your token creatures and doubling the benefits from aristocrat abilities
The only addition is a route in combo example that goes through Planet Pathfinder to Pressured Planet Wraitsoth
The rare costs one more, gives your dork +3/+3 and trample this turn, and then when the dork deals combat damage this turn draw that many cards
You'll be able to find this card in any condition that fits your budget, starting with $5.99 for a damaged copy, eight dollars for a heavily played (HP) copy, and only about $15 for a moderately played (MP) card
