The Treasure generation here is the big draw, but the Goblin-specific buffs give it play in Typal decks like Grub, Storied Matriarch too
I don't think it would be greatly missed if I cut it but I am disinclined to do so as white lacks value
It means that you can use this card's [On Deletion] effect to play "1 red Digimon with [Avian], [Bird], [Beast], [Animal] or [Sovereign] in one of its traits (other than [Sea Animal]), and 3000 DP or less," and if you have a red Tamer when this effect is activated, you add 2000 to the maximum DP for the "3000 DP or less" restriction
The rhino's high toughness makes it hard to kill without two-for-oneing, and the fact that it has trample makes it absolutely necessary to remove
You can only use this effect of "Chaos Dragon Levianeer" once per turn
And were not only talking about a somewhat older system, were talking about a game six years older than this one, and thats a huge gap
