Well I had a truly bizarre match today. So bizarre I wrote a post about it here and I rarely do full posts as I am really pushed for time. https://hive.blog/splinterlands/@sugarfix/newbie-wins-splinterlands-battle-against-all-the-odds

It's not a single card. I think it was the combo that won it as all the cards I had were outclassed by several levels. If you just want to see the battle it is here https://splinterlands.com/battle/sl_b71b6c76783463e93c0d7100fa9c75a1
