Make an All Mid game, no bots, turn on cheats
Pick DK
Type "-lvlup 25"
Level everything up
"-item item_heart" (do this 5 times)
"-item item_travel_boots"
"-allvision"
"-createhero dragon enemy"
"-levelbots 25"
Level up everything for the enemy dragon knight, and dump any of the shit he buys.
"-givebots item_heart" (do this 5 times)
"-givebots item_travel_boots"
Have both DK's stand between enemy's Rax tower and their T2 tower. The creeps will want to kill you, but you're too damn tanky to die so they just stick around you.
Wait 10 or 20 or 30 minutes. Type "-refresh" if anyone comes close to death.
When you feel you're done waiting, have both DK's teleport out, and make sure they stay in their spawns.
Watch the armies duke it out.
