the grand creators booster box Yu-Gi-Oh! 1st Edition TCG since 2002 The Grand Creators - Yugipedia

Shuffle away the cards you dont need and keep only the best options

Cards like Thespians Stage and Vampire Hexmage allowed you to release the Kraken much earlier than intended, eventually leading to Dark Depths being banned in the Modern format

Nissa is very low risk and does reasonable work regardless of you being the aggressor or the defender

Occasionally it's useful to be able to tap things arbitrarily (like if you have that legendary Dwarf) and there are those few cards with the untap cost, but generally green has better mana dorks than this

Tony the Tiger may not have a Magic card yet, but there are plenty of other cool cats who can command your deck
