Let's start with the easy one: Radiant Strike is a new common removal spell that, in all honesty, is likely too expensive to see constructed play at four mana
The downsides of this as a spell are that you have to ensure the deck will reliably have target in the graveyard making it much more restrictive than a lot of good card advantage
The difference in power level between the two is not very much in Modern, as we can also see by looking at our last Top 5 blue cards, which were almost all at three mana or below
Unlike other Secret Lairs that simply reskin existing Magic cards, this one offers eight unique cards and a special Clue token
Its a monster with 2500 ATK and an effect that can Special Summon Level 2 Zombies from your Graveyard, but to play it, you have to control the Trap Card The First Sarcophagus , as well as the Spell Cards The Second Sarcophagus and The Third Sarcophagus
Make sure you have enough ramp (mana rocks, land tutors) so you aren't stuck watching everyone else make big plays while youre tapped out
