You can use Tokens as Tributes for effects, so it would be a good idea to use cards such as "Stray Lambs".
Once this card is in your graveyard, use "Deep Diver" to get a powerful monster on the field quickly.
While it's in your Deck, use "Foolish Burial" to send it to the Graveyard so you can still activate its effect.
Use "Black Ptera" with its effect and it will recycle back to your hand, making it easy to keep the ATK of Dasher at 3100.
This has good synergy with the card "A Feather of the Phoenix". You can use this card as the cost to bring a monster from your Graveyard to the top of the deck then you can use its second effect to Special Summon the monster.
You can also use "Jam Breeding Machine" to tribute one token per turn for its ATK-increasing effect.
Activate "Hand Destruction" during your Draw Phase while this card is in your Graveyard to get a better chance of activating the effect of "Destiny HERO - Dasher's" effect.
If you Special Summon "Elemental HERO Ocean" with the effect of "Destiny HERO - Dasher", during your Standby Phase, you can return the used "Destiny HERO - Dasher" back to your hand with the effect of "Elemental HERO Ocean".
Use "Fires of Doomsday", then Tribute one token for the effects of "Destiny HERO - Dasher" and the other card for its summon.
Equip with "D - Shield" for a hit-and-run attacker that doubles as a wall.
