And when we talk about issues with Reserved List cards going forward, its worth clearly differentiating between cards from this era and cards from, say, Urzas Saga
For example, if you attack with a creature that is equipped with Acquisition Octopus, then use reconfigure to unattach Acquisition Octopus after combat, the Octopus will be untapped and could be used to block during your opponent's turn
The Red one will copy your instants/sorceries that just target your solo stuff, and there is no once turn there either
Most importantly, they don't include shipping which is another checkmark in favor of buylists (since you can generally ship many cards, even thousands of cards, in one order to minimize shipping costs)
If you've completed a dungeon, that creature also gets +5/+0 and gains first strike and menace until end of turn
