The Second Doctor is a group hug creature, who removes everyone's max hand size and lets everyone draw cards, if they agree not to attack you
Then you can exile a graveyard and gain a bunch of life, ramp out two lands of any type not just basics tapped, make a pair of 2/2 Bear tokens, or toss a pair of counters on all of your stuff for the going wide, and with the Bears as a default that's two 4/4s for six mana on a naked board
He's cool
It wants you to ramp by using cards like PuPu UFO and Reach the Horizon to quickly put as many Towns as possible onto the battlefield
You don't want to give someone fuel for an Academy Ruins, toss a Genesis on them, or make them mill a Dread Return
