So I want to build an Alesha deck, but they feel way too similar and I'm dubious in which one should I give a go.

Reanimate, sac stuff, etbs and death triggers is the overall strategy.

Smiles at death brings white, and can have Laughts at Fate in the 99. IIt would be weenie, and White fits on the strat, Teysa doubling death triggers is good. On the other hand, Rakdos seems ok for this as well, and I don't need to be constrained on Power 2 or less, and this is a big differene, and the reanimation on Alesha looks better, not only on the activation cost, but also in the reward.

My question for you guys is: Which one is best for taking the head in a deck? Is personal preference, or clearly one is better here?

Thanks.
