Phyrexian Unlife gives players a second wind by letting them survive when their life total dips below zero

Following the same principle, you can adjust your land count based on the number of cost-effective mana-producing creatures in your deck like Llanowar Elves, or cards that help you retrieve lands like Many Partings, which essentially functions as having an extra land in hand

The Amber and Amethyst deck is probably the easiest to master, while the Ruby and Emerald deck is the trickiest of the three to understand, although its probably the most flexible and adaptable of the three decks

While you could keep casting individual elves from your hand, isn't it better to double the number you already have

That's nasty synergy here

This is why lands which enter tapped are written with a replacement effect instead of a triggered ability: if they came in untapped and then became tapped a moment later due to a trigger, there would still be a window where players could tap them from mana and negate this drawback
