Best Pokemon Card In The World

My neighbor and I exchanged cards Pokemon, and I ended up giving him 16 cards Pokemon rare for a Lucario Lv. X and a Magmortar Level X And some cards have been exchanged, I EX. He continued by arguing that the level Magmortar X was the 9th best pokemon card valued by Beckett Magazine. Is this true? Please help me!

and to be honest me and my friends play "amendment" and my friends and magmortar level X kicks my butt every time. Now that issue is not Beckett rate in the top 10 because I'm number 104 and not on the list of the Top 10. and also the Top 10 ... its more like the number 10 on the list of hot cards that people buy not the best in the world but anyway its definitely a must if you make a bridge of fire change! Make sure you have multiple Magmortars so you can get him out
