Power up Your Deck with Booster Packs
For example, Charizard Ex (from Scarlet and Violet - 151) was recently sold ungraded for $232 USD, but a grade ten sold for a whopping $860 USD
In the second chapter, The Argent Etchings gives all your creatures +1/+1 and double strike, giving you at least 15 power on board across your Incubator tokens, and since they gain double strike that's 30 damage you can send your opponents way
The Chase Cards Collector focus centres on alternate-art, borderless, and raised-foil Headliner versions
I tried to order the proxy boosters first, but after adding the custom cards to my cart, it wiped out all my previous ordering
For cheaper than buying them individually, you can get Food And Fellowship, Riders Of Rohan, Elven Council, and The Hosts Of Mordor, complete with their Collector booster sample packs
