Too many cards in a deck

{"ops":[{"insert":"I see a spellslinger sub-theme in your deck that probably got a bit parasitic while you were building. Some of these cards support your main theme really well. Others not so much. In general, I would look at those cards and cut the ones sapping resources from your strategy. \n\nExhibit A: "},{"insert":{"card-link":"Guttersnipe"}},{"insert":" \nBasic spellslinger payoff; serious threat in the right deck. In your deck it's a distraction. Sort your deck by CMC and look at the cards it's competing with for mana and sequencing.\n\nExhibit B: "},{"insert":{"card-link":"Rionya, Fire Dancer"}},{"insert":" \nThis card needs a creature to copy and instant or sorcery spells cast on your turn prior to combat. Because this is a 5-drop, you're probably meeting all the conditions to benefit from this card on turn 6 or later. This could be a setup for a really cool turn 6, or you could get to combat on turn 6 and realize you completely wasted turn 5. Based on the other cards in your deck, I would wager the latter happens more often than the former.\n\nI would do similar evaluations for all the cards in your deck that care about casting instants and sorceries. If you're still over 100 after that, I would cut anything that doesn't solve a problem, support dice rolling or help your commander attack.\n"}]}
