This card is win-moreish. It rewards you for going wide, but what if the opponent has interfered with that plan? What if you are on the back foot? Sucks to be you, I guess.

The card conflicts with itself a bit. You want your "all your creatures are unblockable" card to be the last card you play in a game, but you also want to have time to cast the cards you draw with it. It also is a little too expensive to leave mana to cast the cards you draw in the same turn, and also leaves you open to a counter attack, making the whole package very narrow. Overall, I think the card is quite mediocre.

Embalmer's Tools is garbage.
