mtg graveyard hate cards Modern Top 5: The 44 Best Graveyard Hate

I think this is fine, you need some swing cards else you play too fair and just get beat by something unfair

Thats because it causes a target opponent to have to exile the creature or planeswalker they control with the greatest mana value among the ones they control

Moreover I've read that if I use sleeves the card is most likely to be accepted by the judge

If you want to fight delve against a deck that uses it like they use Tarmogoyf, might I suggest Relic of Progenitus

From void evolved Phyrexia

So my recommendation to investors is to study the RESERVED LIST and start picking up cards that are within your price range
