I've started playing magic not too long ago and need help fixing/tweaking this deck.

Played test it a bit and normally works but looking for new answers to the main and perhaps help making a sideboard as it only contains extra alpha authories and unused spells. App basically empty

Cool deck! Maybe instead of Experiment 1 go for {Gyre Sage} for even more mana!
