Thats nice, but it also puts a +1/+1 counter on any nontoken creatures that enter the battlefield under your control, and lets you draw a card when you do so
The illustrations are a treat, and so are the mechanics
The simplest format for a list of Magic cards is a text file containing the number of copies you own and the name of a card on a line by itself: 2x Mimic 1x Mordenkainen's Polymorph 2x Ray of Frost 4x Sol Ring However, the application supports many formats, including a CSV from Magic: The Gathering Online, TCGPlayer table, MTG Studio, Apprentice, DeckBox, and more
Its super simple: Play every variant of Doomed Traveler and Krenko's Command you can and turn those tokens into 6/3 menace creatures
Theres nothing more to say
What's an opponent supposed to do
