The bottom line is if you cleared the previous floors while losing hardly any creatures without trying to rush, then yeah. But if you won trading blow for blow, well now your trading blow for two blows and it’s not in your favour. : P
The primary concern is the enemy has more spells, hard removal, from 8 damage smite to 9 damage fireball with scorch follow up, let alone the petrify on top~
That taken in mind if you used a magic reflect decks the angel rush, then yes it will work fine even if the enemy draws double since it will just rebound and the cards will kill themselves. Same thing for physically immune cards vs the arbalest/warrior deck.
Against the all-out half-blood rush it will vary as it can have the ranger removal cards and high burst first strike double damage, which is a problem when you have effectively half the minions to tank double the damage.
I strongly recommend you evaluate your deck:
+ Are you P2W? If so odds are you can clear tower with 2 deck comps and relative ease.
+ Are you a long term F2p/Fremium player? Then build general deck, I recommend, any hard rush (preview: peg/knight/windwalk), anti mage deck (preview cards with nimble/thunder), and anti-arbalest(preview: crossbow, arbalest, priests), anti power deck (preview: all 3 cards 5 turns+)
