Tokens, counters, blinking, and artifacts are all fun strategies, but its not often that they all work well together
Ashened to Endlessness X TRAP Continuous During the Main Phase: You can Fusion Summon 1 Pyro Fusion Monster from your Extra Deck using monsters from either field, including "Veidos the Eruption Dragon of Extinction", and if you do, it gains 500 ATK for each material used
If you want to make a competitive deck, you need dual lands, fetch lands, and other extremely OP staples
Cost reduction has the benefit that it can be played as soon as turn one (if using Kinjalli's Caller) and scales very well when casting multiple Dinosaurs in a turn
You're likely to see only one or two of these cards per game, so be careful to cast them when you know they'll be safe from counterspells and disenchants
