The Leonin Scimitar is in just 609 decks, but it seems very strong with one mana card drawing Sram, Senior Edificer (993 decks), or the mad card flow of the attack trigger of Wyleth, Soul of Steel (1969 decks) as two commonly played examples
This task delights me in real life, as I sit in the center of a huge fan of colours and gorgeous artwork, neatly sorting decks into piles, hyper-optimising for a particular mechanic before I get to try them out in a game
Sol Ring Look, we all know what Sol ring is and does
He is one of the strongest creatures with 12/12 stats and his Trample ability allows him to deal the excess damage to your opponent, giving them a difficult choice between blocking with a cheap creature or just letting it pass through for a lot of damage
Make a card that can be played for no cost and Timmy is intrigued (as are Spike and Johnnybut hey, they're human too)
