Mulligans
General Mulligans
Plated beetle and raptor because they are low cost value cards. The secrets are good, for two different reasons. Wandering monster is good at getting a high value minion down early, as many people will have early threats and most will hit face, Explosive trap is good to have early on, as against early aggro decks, you can use to neutralize a big board. Loot hoarder is good in order to get deep into your deck fast.
A deck focused around deathrattles. Mainly, having them and making them as effective as possible. Also includes a few secrets, and a few removal spells, along with Rexxar for continued minion generation.
