Blood Artist Blood Artist and its many imitators are among the most reliable damage sources in aristocrat decks that might otherwise struggle to close out the game as they fiddle around with Putrid Goblin, Yawgmoth, Thran Physician, and similar cards
Here's a graveyard abuse deck that won't break your bank, just your battlefield
Thickness of 1 Side (microns): Vault X Exact Fit (60), KMC Hyper Mat (115) 100 Double Sleeved Card Thickness (mm): Theoretical (65), Practical (69) Water Test: Pass Deck Box Fit (mm storage): Fit: 59 good, 41 bad
These combine with abilities that deal direct damage, produce creature tokens, and grow your creatures each time you draw that 2nd card
However, don't let this list fool you, if your metagame is different/silly then those cards might be just what you need in every deck
