If you built your deck to win with a certain combination of cards you can just sacrifice life until you have them all in your hand and then win, all in one turn.

It's kind of a lazy deck archetype that typically doesn't require you to pay attention to what your opponents are doing or interact with them in anyway. You just sort of play solitaire until you have your combo. Victories with this strategy feel cheap and hollow, and losing to it feels worse. The general strategy of sacrificing life for card draw is still valid though, but wotc usually designs mechanics like this to make sure the risk vs reward feels fair (a hallmark of black cards). However, this particular card was too easy to exploit and is no longer legal in most formats.

There are some cards that cause you to gain 1 life whenever you draw a card, which would negate the cost of this ability and let you draw your entire deck, which would also be bad for you if you ever had to draw another card for some reason (such as from your draw step) and would cause you to lose the game from the "not being able to draw a card from your deck" rule. unless you had a way to put cards back into your deck so you could keep drawing from the top of it, but at that point what are you even doing lol

That's all the lore I have to dump out of my brain about this particular topic. I hope someone can find something in it that is useful or insightful in some way.

I just realized this was the dunk tank. Oh no my time
