Diversify Acquisition Methods To build a flexible and cost-effective collection, collectors should utilize multiple acquisition methods: Booster Packs and Boxes : Ideal for discovering a range of cards and potentially pulling rare finds
Avenger of Zendikar has a 90% chance of making the deck, imo
Indoraptor, the Perfect Hybrid The mana cost on Indoraptor, the Perfect Hybrid makes it a bit weird to fit into a Cube, but its reasonable to just slot it in as a Gruul or Rakdos card, and some Cubes just have space for gold oddballs
The delayed triggered ability created by Leori's last ability, as well as the copy it creates, resolve before the ability that caused it to trigger
I like those odds
Ideally, you can start out early with cards like Siren Stormtamer and Fathom Fleet Captain, then cast your commander on the same turn you plan on fulfilling her end step trigger
