At the end of the match, the winner would take and keep both cards
Other Builds If you want a different spellslinger version of Riku, try instant and sorcery spells with flashback with a few cost reduction effects like Catalyst Stone
While there are other weird things you can do with activated abilities on creatures, the bread and butter of the deck will be cards like Will, Scion of Peace for cost reduction, Beacon of Immortality for big mills, and Sphinx of the Revelation to draw a lot of cards
Fabled reprints keep her in Core Constructed and give a solid choice of a proven finisher
Both of these options are going to be absurdly powerful in different situations, and were really excited to build around them
I simply think the current approach to the issue isnt realistic as it relates to understanding the player experience with the current product lines, and something should be done very differently
