This page is about some easter eggs in Undercards history.
Royal Guard Easter Egg
If you had RG 01 and RG 02 on the field:
RG 01 will say "..." in the effect box.
RG 02 will say "Armour so hot..." in the effect box.
This easter egg no longer works, since the RGs now have a Dust effect.
Get dunked on Easter egg
If Sans destroys Chara from the opponent hand, he will say "Get dunked on ! "
SECRET UNDERCARDS EASTER EGG! SANS KILLS CHARA! (GET DUNKED ON!) - UNDERCARDS LUIGIKID VS. DEVELOPER
LuigiKid VS Onutrem. LuigiKid pulls off the "Get Dunked On" easter egg.
Since Sans no longer kills cards, this sadly no longer works.
