pokemon lunala gx card TCG - Sun & Moon Full Art Holo 66/149 Preserved in a tamper Tcg Lunala GX - Sm17

I think the Armor is a bit better in most ways, including an easier equip cost, flash, and the protection upon entering

The card started an entire generation of Shiny Vault collecting culture

When do I play that card

There's no real way around Smothering Tithe, and two mana is a lot to pay, so more often you'll be constantly getting Treasure tokens since your opponents won't want to pay for it if they want to cast any spells

Given the relatively low cost of the D23 set at the original event, if you bought it and youre currently holding onto the set in your Lorcana collection, you must be very content with your purchase
