Revitalizing Repast // Old-Growth Grove

The front half staples two effects onto a single mana that usually do not travel together: a lasting +1/+1 counter and indestructible through end of turn. Most cheap protection spells spend themselves saving a creature and leave nothing behind, and most counter effects assume you are already the deck committed to a board. This does both, so the mana you spend surviving a removal spell or a doomed block also permanently enlarges the creature you rescued. The indestructible clause answers a wide slice of the kill-spell pool (destroy effects, damage-based sweepers, losing combat) while leaving bounce and exile untouched, and that boundary is the reason a one-mana trick does not read as a universal shield.

The reason it takes this shape is the back half. Because it is a modal double-faced card, the combat trick you drew but do not need converts into a tapped land that produces black or green. That solves the oldest liability of narrow tricks: they clog opening hands and stall out as topdecks. Here the floor is a dual land and the ceiling is a proactive protect-and-grow spell, with the only cost of flexibility being the tempo hit of the land entering tapped when the land mode is the one you want. The deckbuilder trades nothing but a turn of speed for the guarantee that the card is always doing something.
