You can choose five flips during each of your combat steps without the potential risk of losing 10 life, drawing yourself a good number of cards in the process
A deck that includes several creatures with +1/+1 counters, such as a +1/+1 counter synergy deck or an aggro deck focused on building up creature power, would benefit from including Twisted Spider-Clone
It's arguably one of the best cards for Type Four from the set (Rules are - infinite mana but just one spell per turn so counters are good there since they cannot be overwhelmed by casting more spells than you have mana, and a five cost counter is first turn able there)
There are 21 cards with learn and there are twenty Lessons to find with them
Organization: Dividers or compartments help keep cards sorted
Just remember at 6 mana, its not exactly a quick drop, so pack some protection to keep your bloodthirsty boss alive once it hits the table
