If you're a Rakdos fan or play with the aggressive and unpredictable style of the guild, these sleeves are a great way to show your love for chaos and protect your cards
With that disclaimer out of the way, I'll give my 2 cents anyway :p I'd suggest examining these cards to see if you can replace them with cheaper CMC or more synergistic alternatives: Portal to Phyrexia Maelstrom Colossus Koma, Cosmos Serpent Basically, I'd examine any spell CMC 6 or higher personally, I find once you get into that range each card should be something you enjoy and can't replace
Any other questions required me to break out the rules and regulations book to explain things further
Once per game, any time you could cast a sorcery (during your main phase when the stack is empty), you can pay 3 generic mana to put your companion from your sideboard into your hand
On the other hand, some of the basement uncommons can go backwards in time to spice up an old-school set cube like Alara
