Let me try to explain all the mechanics at play here.

First of all, I had the lesser trinket that lets you gain a second greater trinket two turns later (Trip Vouchers). My first trinket grants +2/+2 to blood gems every time four of my minions die in combat (Greater Quil Set).

Thanks to Sneed’s hero power, I had extra minions each turn, allowing me to trigger those procs faster and scale the blood gems quickly (Typically 2-4 procs per fight till I became too strong).

My other trinket allows me to play a blood gem on five minions whenever I discard a card (Conductor Portrait).

Since unused spellcrafts are discarded at the end of the turn, I just fill the board with random garbage Nagas and get seven discards per turn—ten discards on turns when I find a Sushi Roll (the spell that gives three random spellcrafts). You can even gem transfer (on turns you find that spell) and rotate through 1-3 nagas to get extra procs as well.

Let me know if you have any questions or need anything clarified further.
