Lord Jaraxxus equips a weapon that is inactive on opponent turn so can't be detroyed by Acidic Swamp Ooze it's 3/8. His hero power becomes "summon a 6/6 infernal to the filed" ofc these summons will have resurrection sickness.
If you see a card that does sth on summon it includes totems and tokens if you see it write play a minion then it's only if you summon a a minion from hand. Meaning if you play Razorfen Hunter itself will count but not the boar.
all minions meaning your's and opponents but not heros. It procs from itself and all other minions in play.
Sorry, what i meant about Frothing Berserker is: minions gain +1 attack when damaged, the hero gain +1 attack when a minion is damaged or Frothing Berserker gain +1 attack when other minions are damaged?
