For those of you with neutral Brave Lyn

The arena is swarming with Brave Lyns because people picked her as the free summon, and you did too (probably) if you're reading this. All these brave Lyns have neutral speed (38) but this can actually very easily be exploited in your favor. Take your Speed +1 sacred seal and put it on your own Brave Lyn. Your speed will become 39. Swift Sparrow makes your speed go to 43, which is enough to double and kill an opposing neutral speed Brave Lyn. A reliable counter for Brave Lyn is actually herself.
