Base toughness counter

Base toughness counters are a unique counter type introduced in Mystery Booster 2 on the test card .
==Description==
Base toughness counters change the value of a creature's base toughness for as long as the creature has that counter. The counters are unique in that each has an assigned value that they modify the creature by. 
The counters essentially replace the printed toughness of a creature but only affect the base stat. Other continuous effects that modify power and toughness, such as the ones created by <c>Giant Growth</c> or a +1/+1 counter, apply after the creature's toughness has been changed.
Base toughness counters do not alter a creature's power.
