Golden Lion

[Elia41]

Here is the "evolution" of my previously posted card, Brass Cub. This is Golden Lion, my new Synchro Monster

 

Effect:  1 Tuner + 1 or more non-Tuner monster.
When this monster is sent to the Graveyard, you gain 500 Life Points and the Synchro materials return on your side of the field.

 

Way to make an attack backfire ...

It's not the strongest Level 6 Synchro, but with it being generic, along with the mandatory float effect, it has some uses, especially if you use materials with effects that trigger on SS. Now to fix the OCG:

 

1 Tuner + 1 or more non-Tuner monsters
When this card is sent to the Graveyard: you Gain 500 Life Points, also Special Summon as many monsters in your Graveyard as possible that were used for the Synchro Summon of this card.

The best use of this card is obviously in Beast-Type Decks, while I can imagine it in other concepts too which uses Tuners but needs some generic Synchros. However, with the return of Goyo Guardian, I don't think that this card would see any play neither in competitive nor fun environment (as Gaia Knight still exists along with other LV6 Synchros too). The 500 Life Points isn't doing anything on its own, however, its other effect is rather effective, but I'd change the "sent to the Graveyard" to "leaves the field" for other techs, or add a bit better stats.
