Is it really worth it to write about preparing for rotation when only a handful of cards have any meaningful amount of value
Madness makes Emrakul go to exile rather than the graveyard, the madness trigger goes onto the stack, and when it resolves, you have the opportunity to pay the alternative cost right away if you want to cast it, else our Eldrazi friend will be moved from exile to the graveyard (as if it had been discarded normally)
Nevertheless, there are rare cards with special types of artwork that are actually very cheap and worth grabbing while their values are still on the lower end of average for Illustration Rares and Special Illustration Rares
The former counters Glaceon ex effectively due to Arceus exs high-damage attack and Crobats Bench-sniping ability
All but the two Unstable cards have been played against me though.
If you dont have a printer or need to print something bigger, you can go to your local Staples, Costco, etc
