I'm waiting for the power
reset to come about. Every few sets like this, Wizards raises then drops the power of cards, and so the cycle goes on. This is a very powerful set. Adventure cards have a unique
brand of card advantage, but I see them as slightly better Aftermath or Flashback style effects. They are just Spells that become Creatures, instead of the other way around. What makes them better is you can cast both halves, then return one card from the graveyard, then cast both halves again. Whereas the other variants usually end up in
exile instead of the graveyard.
I think having instants on creatures is fine. It's (usually) a common or uncommon level effect on a common or uncommon body. The only one I have a problem with is Brazen Borrower because it is TWO instants. The
Disperse is not the problem, it is the free body that you can play at the end of your opponents turn while holding up a
counterspell or other removal, then start smashing face.
Murderous Rider - great card, but totally fair. You cannot play it when you are low on life because it can kill you, and you cannot return it from the grave to your hand.
Bonecrusher Giant - also great. Removal, a large body, strong effect on creature, and gets around protection effects. Still gets chump blocked and killed by so many cards
Adventuring Beast - totally fine. I think it might be a little weak even, because if you kill or even pump the 1/1 token the Beast cannot attack.
Giant Killer - not great, but fine. 1 mana 1/2 with a 2 mana tap ability is a little slow, and no one really plays
Smite the Monstrous anyway. This is the 'missing' white card you are talking about.
As for
Lucky Clover, I love the card. A 2 mana do nothing card, that allows you to gain advantage over a few turns is great. Two shocks is really good, but not game
breaking. 2
Bedevil is fine, but you lose 4 life which can be a lot. 2 1/1 tokens is laughably mediocre, but allows the Beast to attack more consistently. 2
Smite the Monstrous is... okay I guess, but if there are 2 large creatures you might be in trouble anyway.
Even bouncing two things isn't that groundbreaking, but the 3/1
flash flier is what will kill you the fastest, and bouncing your threats keeps you off of your
game plan long enough for it to end you faster.
