For players looking for more budget options, you can substitute this card for Sorin Markov, which is about $10, or for another vampire creature card of your choice that synergizes with your idea of a great vampire deck
Theres an abundance of ways for you to untap Szeras and sacrifice a few creatures in the same turn to generate a ton of mana since its an artifact, but those creatures need to have cost a lot in the first place
Blind booster purchases from Modern Horizons 2 or 3 carry significantly higher financial risk than Foundations or Innistrad Remastered, where the card pools are more balanced and fewer cards are 50+ outliers
The reference ladder is NM, EX, GD, LP, PL, Poor
If your game plan is to win with a giant attack from a single creature, consider this as an inoffensive way to make that happen
That is about the only criticism I have of the card, that and it is boring to play against because it takes so damn long to do it properly
