If you look at a typical Infect deck list all of its creatures are Phyrexians thanks to an errata a while ago, so The Seedcore works as a dual land (this is could also help open up the possibility of more three-color infect builds rather than the two-color builds which are most popular today), and almost all the most popular Infect creatures are 1/1s, which makes The Seedcores corrupted pump ability especially impactful
The degree of success you can expect with your deck vary of course, but you can basically play anything you can think of
Since thats not our present day, Cindervines likely stays on the bench, but its a fine card to add to our Modern binders in case things ever line up just right
While there still are some standout cards that could do well over time like the Piplup and Meowth Illustration Rares collectors looking for a wider range of valuable cards rather than one great whale of a chase might prefer other packs
But you get to cast the real one later for free, so the best pattern is to play a cheap spell first and a bigger one later, like a Time Warp or Stock Up
