I am favouring Conduit of Worlds mostly as it is not limited to converted mana cost (CMC), as many of the big effects are higher CMC while also letting you double dip by replaying the lands for free
Will The Cards Be Worth Anything
Remember, though, that the value of a card can fluctuate over time, and theres no guarantee that your investment will pay off
Examples include the aforementioned Dondozo and Tatsugiri deck, as well as a deck of Koraidon and Revaroom cards that allows players to put fighting energy cards into the discard pile, before moving them all onto a basic Pokmon
If you do, this attack does 40 damage plus 20 damage for each basic Energy card you discarded
