All this week (and shortly into next) brand-new cards will be popping up on DailyMTG and around the internet, so stay tuned to the Card Image Gallery and the list of preview outlets to find all the cards coming in Core Set 2020
Yes, loads of cards are better in the right situation, most creature removal spells are better in the early game, but Trophy is comfortably the winner on average
This set inspired me to think about a Cube where you had 100 of each basic land for your players, and every single one had different art
Heliod, the Radiant Dawn is a very straightforward commander in this way, costing a fairly cheap four mana to transform him, or three mana and two life, to compleat the poor god, turning him into a twisted, Phyrexianized version of himself
One of the best cards from these sets is Grave Scrabbler, which still sees a fair amount of play in formats like Commander to this day
