In addition to forcing each player to skip their discard phase, Anvil of Bagardan grants each player an additional draw at the beginning of their draw phase, but then they must choose and discard a card from their hand, offering those playing with graveyard shenanigans the free discard outlet they would have gotten at the end of the turn but now just at the beginning, meaning they could take advantage of it during their respective turns
For example, you may only play a land this way during your main phase while the stack is empty, and only if you haven't previously played a land this turn
This isnt classed as turning the card face-up, so any effects that occur when this happens dont trigger
This swords abilities synergize well together, as exiling two lands goes well with playing extra lands
This combo needs 4 cards: Clever Impersonator + Saheeli Rai + Sun Titan + Karmic Guide
Ill list a number of different ways you can incorporate the graveyard into your builds, regardless of the color(s) or strategy
