This is a example fossil Hypnos prophecy attack normally allows you to look at the top 3 cards of your deck and rearrange them but instead of that it has you look at the top 3 cards of your deck then you draw 1 of the cards and discard the other 2 then shuffle your deck
Oops I just realised I left something out lol you also have to discard a energy card from Hypno and the energy cost for prophecy is now 2 psychic
As someone who’s been obsessed with making up custom cards since '99, I wouldn’t mind an attempt at retconning and trying to rebalance/diversify retro formats with a handful of custom cards to take the place of useless filler cards. If I ever get around to printing some proxies I’ll also include some customs in this vein.
