Magic: The Gathering - 10 Most Powerful Mono-White Cards In 2020 Standard
1. Elspeth Conquers Death
The mono-white card currently present in the most decks in standard, and arguable the most powerful, Elspeth Conquers Death. Three generic mana and two white will get you this Saga. Hard removal, taxing your opponents spells and reanimating the best card from your graveyard, three powerful affects on a single card make this worth an an include in any deck that can take it.
When it enters the battlefield Elspeth Conquers Death lets you exile any permanent your opponent controls that costs 3 or more total mana. Hard removal in white, this is one of the few places it can be found. The next turn it does nothing for you, but it does put a two mana tax on your opponents' non-creature spells.
This makes the possible removal or bounce spells they may play that much more difficult to cast. In a sense this protects your side of the board. Finally you get to bring back any Planeswalker or creature from your graveyard that found its way there through either your or your opponents actions. Oh it also come back with either an extra loyalty or +1/+1 counter, just for fun.
Providing incredible amounts of value for a relatively low cost; if your deck has white in it, it should also have Elspeth Conquers Death.
