Titania, Rugged Rumbler

A 5/5 for three that taxes both ends of its life: you pay to get it down, and your opponents pay to interact with it. The additional casting cost and the ward clause share the same currency (discard a card or pay ), which turns the whole card into a repeated toll where a spent resource is always the transaction. That symmetry is the axis to sit with. Most ward creatures make interaction expensive only after they resolve; this one front-loads the same fee onto the caster, so the body arrives already having cost you something, and it keeps demanding payment every time someone tries to point removal at it. The hybrid pip means the card lives in either black or green without a splash, and both colors are happy to pitch a spare card rather than bleed mana. The statline does the rest: at three total investment, a ward-protected beater that outsizes most early blockers and forces a two-part answer (first the discard-or-pay to target it, then whatever the actual removal costs) is a genuinely awkward thing to kill on curve. The friction is not a keyword bolted onto a vanilla body; it is the same tax expressed twice, once by the caster and once by everyone who wishes the caster hadn't.
