I just went through the entire topic again. After fighting Big Blue for a while now with my mid-level Renally deck, a few things to note:
1. Dryad Backlash - will stop Renally from achieving that unstoppable amount of pwnage
2. Sylph/Undine Backlash - stop the silly buffs the other guy keeps getting on owning your unit because Legyre has such high ATK
3. Lv3 and above owns
Against big blue, you don't hit souls. You don't let them build sp either. I think we've come to a conclusion that SP drain really slows Big Blue down from activating it's super ownage. But SP drain = death from any gowen rush or low level rush type decks. So through this topic, a triangle was formed saying that there is no overall system that you could add your own unique flavor to compete with these decks. Another to add is that assassin is OP as some people may say.
I think the simplest thing to do is to keep on with what you want to play. Be sure you have a good number of lv3+ as well to keep your stand hold against this deck. Cudgel is a really good unit to play along with plenty of other Refess units to bring the ownage to any big deck.
Cudgel and Angel's trumpet are a great addition as it doesn't stop just big decks but others around in Folrat from starters -> modified starters -> original decks.
If you don't have any way of incorporating Cudgel or Angel's trumpet, and are using one of the following starters... let me advise you to do the following:
20 x lvl damage cards early in the game really hit the big units hard! Make this a second and/or third soul and you'll do pretty well.
Add sylph and/or undine with two dryads if possible to backlash own. Don't be afraid to add a Chiruru soul. More lv3s than lv2s or a rogueest to boot! Make sure you can do this by round 3. Be careful of cyclone by round 3-4.
Same with the Gowen starter, you want to miss your first turn and bring out the sea hunter / magic scythe or other lv3 combo fast. More level 3s and Azure Dragon out to help and you've got the game on wrap. Be sure to predict undine/sylphs for backlash, this is really important.
Cudgel Cudgel Cudgel, or a Chiruru soul. 20 x lvl damage cards are your friend here too.
