Feels your pain man. Even with a gold Legendary froggie card level four gives me trouble with other lower cards.

It takes a lot of cards to make a level six card. It takes:

2 LEVEL FIVE
4 LEVEL THREE
8 LEVEL TWO
16 LEVEL ONE

With the going rate for a common level one blue frog being 250 volts, it would take 16x250= 4000 VOLT to get to level 6. That's about $4.00 per card!

You appeared to skip Level FOUR. It's 32, just double of 16 even.

4 LEVEL FOUR, 8 LEVEL THREE, 16 LEVEL TWO, 32 LEVEL ONE

Bringing it to 8000 VOLT (to get to Level 6) Moar like $8 per (Level 6) card!

Thanks for sharing, have fun, and good luck! !BBH !DIY !DOOK
