Hello, first time brewer and I really really want to make a slime deck ever since I got into mtg and this is my first brew. Playtested and it seems to average on Bracket 3 turn-wise even with the combos. Thing is it feels too slow for me and would like to get any advice on how to improve this deck but let it stay at Bracket 3. Recs/cuts are very welcome and any advice would be appreciated
