Well, Bronze shield is directly outclassed by Blue Sky Knights, Iron Wing Dragon, which has 1k more power. Also, 6k defense is becoming less and less revelant, with all the 6k size 1's, and 6k weapons, it doesn't help nearly as much as it used to.

Logically, 6k defense. Adventurers-love link attacking anyway. Ancient- Giant monsters that will easily overcome 6k defense. Danger- Explosive Axe and Lizardman. Dungeon Enemies- that one staff that gives all Dungeon Enemies +1k attack and +1k defense (which is the build's favourite weapon), combined with any 5k attacker (especially Bladewing Phoenix). Armourdragons- Blade Chakram. Dragon Knights- Lawrence. Magic world- the Gunrods. Katana- you got them there. Even Darkness Dragon World, the buddy Rare has 6k attack at size 1.

With Galvanic, you pay 2 gauge for a vanilla size 2's stats, 1 if you count his 1+ gauge from his first attack. His second ability eats all of your gauge, which could easily have been put to a better size 3, or Jack, an impact, or as El-Quixote said, to protect yourself with Dragonic Thunder. And again, with 6k defense being less and less useful, he's pretty fragile.

With the destruction cards, Monsters are superior to spells in most cases. Spells do their job once and are done, monsters can either keep attacking, or draw attacks away from your health. Dragon Breath's target line is too small for it to be consistant (my friend who used that card, could only ever hit my size 0's) but dragonic thunder is good for obvious reasons.

Hope you can answer your question. And I hope my rambling teaches you something.
