Vigilance, reach
When Harold and Bob dies, if it was a creature, return it to the battlefield. It's an Aura enchantment with enchant Forest you control and "Enchanted Forest has ': Add three mana of any one color. You get two rad counters.'" Harold and Bob loses all other abilities.
Cast Harold and Bob early as a 3-mana vigilance/reach body, then intentionally kill it so it returns as an Aura that turns one of your Forests into a 'tap for three mana of any color' rock—giving mono-green decks both explosive ramp and full color fixing. Use that surplus mana to power out enormous threats, X-spells, or mana-hungry combo pieces while the rad counters quietly fill your graveyard for recursion payoffs.
Add the cheapest and free sacrifice outlets (Ashnod's Altar, Phyrexian Altar, Birthing Pod) so you can convert Harold on your terms the turn it lands. Stack untappers and mana doublers—Seedborn Muse, Vernal Bloom, Vorinclex, Nyxbloom Ancient—to turn one Forest tap into a windmill of any-color mana, then add a deterministic mana sink like Walking Ballista or Finale of Devastation to close. Tutors like Green Sun's Zenith and Worldly Tutor improve consistency, and proliferate or graveyard payoffs let you turn the rad-counter downside into card advantage.
