The order doesn't mean anything (well, other than I'm capable of alphabetization)
The mono-white version of Cloud focuses on Equipment, triggering his own and his Equipments' abilities an extra time, allowing you to double-up on benefits and build Cloud into an unstoppable behemoth
The boosters are compatible with other Jumpstart packs as well, so you can keep the mash-ups going once you have worked through the Avatar box
Remember that a creature is still attacking during the end of combat step, so sacrificing it to Goblin Bombardment or Altar of Dementia will still trigger Brazen Cannonade
Great Gift Idea: Makes the perfect gift for Disney fans
After all, theres nothing worse than playing a massive green creature, only for it to be killed before it can ever attack
