The ability is a black-red mini-theme and it shows up on one mono-black card (Dread Wanderer), two mono-red cards (Hazoret the Fervent and Thresher Lizard), and one black-red card (Neheb, the Worthy)
The downside is that they have stipulations in their tutoring abilities like Demonic Counsel requiring you to have four or more card types in your graveyard and Diabolic Intent forcing you to sacrifice a creature to go digging, but thats not really a problem in most games
The biggest issue comes from sequencing
Even more so, you can eat up the little 1/1s to make the big guy even bigger and create more tokens when it attacks
Maybe the budget option is better for you as well
Being able to enchant a permanent is a marked increase in power level that you might not pick up on straight off, and one that makes me excited for the future
