Riftwing is OP

https://splinterlands.com?p=battle&id=sl_9e41506ade7992582e9a60ab49d651db&ref=gh-favel
I just leveled my Thaddeus to level 4 today. I leveled riftwing and the other death commons to 5. I leveled my windeku and djinn murrat to 4 and 2. I did a few others also.
I was lucky to get a death quest, so I decided to try it out. There's a huge difference between level 4 and level 5 riftwing. I actually skipped this battle when he hit the front, as I thought it was clearly over. My riftwing got 12 misses and took out the entire back line. They were all opportunity and sneak. Not only did he carry me with hp, he was also my top damaging unit this round. I've never experienced Riftwing dealing damage before. It's always been a scavenger 3rd tank kinda thing.
Is there any amplify in death? If so please lemme know. I'd like to try it. If anyone wants to delegate one for a day or two my ign is "gh-favel" and I play silver tier currently. My next summoner will be quix I think. Then I'll go back to obsidian get her to 5 and move to tarsa to 6, obsidian 7, tarsa 8 obsidian 8 quix 3 kelya 8 Sloan 8 Thaddeus 8. Its going to be a long process. I might not finish in time before packs sell out or prices shoot up, but till then I struggle.. Thanks anyone that watched or read. -Favel
