Breaking / Entering The Breaking half of Breaking / Entering is just a toned down Glimpse the Unthinkable, which is a nice card to have in mill decks (or if you want to mill yourself, eight cards for 2 mana is a good rate)
You have nearly a complete engine with your commander's ability to draw into creatures and the means to pay for them
When it enters, you choose a creature type, hint: choose Turtle, and it doubles every triggered ability of your creatures of that type
Notably, it incorporates a dynamic weather system
What does Well of Ideas do
During the opponents turn, Gumblar will discard another 2 cards, leaving the opponent with only 1 card left, and that could be negated by a Borreload Savage Dragon or Hot Red Dragon Archfiend Abyss
