Interesting list. There's a couple of combos that just go off with just Stella. Cerulean whisps let's you draw your whole deck targeting Stella (there's twitch and one more that do the same untap and draw effect) And Twisted Fealty simply let's you win the game by itself with Stella instantly. Cerulean whisps is a bit pricy at 5€ but the rest are fairly cheap. From playtesting the deck needs more cantrips and has a bit too many creatures. There's also Harmonic Prodigy a two drop that adds another trigger to shamans and wizards (guttersnipe) and comes with prowess. If the whole combo infinite stuff is too competitive for you (it was a bit much for my group) focusing more on triggers and tokens is way more fun and gets out of hand by itself. Eris is the mvp in that sense.
