Usually, when an expansion set involves tokens that already exist in the block, we don't make new token cards for them. But New Phyrexia is different! Sure, there was a Myr token in Scars of Mirrodin. But that was a Mirran Myr. New Phyrexia brings something new to the party!
Ooh! Phyrexian-y! Hey, do you think any other standard creature types might show up in compleated form?
I guess so! But what about something more in theme for the block? Maybe something that gets created fairly often?
Perfect! But how about a token that doesn't already exist in the block? Could we get that taken care of?
