Coming into effect on the 29th of May (right now) for paper, and on the 30th for MTG Arena, three cards are being banned in Standard, these cards are as follows: Fable of the Mirror-Breaker // Reflection of Kiki-Jiki Invoke Despair Reckoner Bankbuster With two of these cards being leaked ahead of schedule, its completely unsurprising to see these cards being banned
There are also key synergies tokens, and my favourite, artifact aristocrats, getting the most out of cards like Skullclamp or Ichor Wellspring
That being said, Duskmourn: House of Horror has been out for a bit now, and this card is still expensive
Let me know in the comments), Regal CaracalRegal Caracal is a bit pricier than most lords you expect to cast (except for say, Raksha Golden CubRaksha Golden Cub)
You don't choose a target for Boilerbilges Ripper's ability at the time it triggers
These boxes are usually cheap, but mostly durable
