Sandman, Lord of All

When Sandman enters the battlefield you may search your deck for a Minion creature and put it on the battlefield tapped.
Sandman's power and toughness are equal to the number of tapped creatures you control.
{b/r}{u/b}: Tap a target Minion creature you control, if its toughness is below 2 it does not untap in your next untap phase.
